The MAXREFDES1034 is an auxiliary power supply for TV applications. This design provides a 5V output and up to 5A of load current for system power of auxiliary functions such as monitoring and control. A wide operating range from 11.5V to 28V allows system designers to adapt this design to their input voltage needs. As with most modern TVs, flat panel screens limit the available area for the converter. This power supply is a low-profile design, which considers modern TV sizes and available space. This design focuses on providing high efficiency while limiting the total height to 6mm.
The MAX17690 is a peak current mode, fixed-frequency switching controller specifically designed for the isolated flyback topology operating in Discontinuous Conduction Mode (DCM). The device senses the isolated output voltage directly from the primary-side flyback waveform during the off-time of the primary switch. No auxiliary winding or optocoupler is required for output voltage regulation.
The MAXREFDES1043 is designed for SpO2 measurements based on Maxim’s new-generation biosensor—the MAX30102.
Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity. The MAX17690 eliminates the need for an optocoupler or auxiliary transformer winding and achieves ±5% output voltage regulation over line, load, and temperature variations.
The MAX17595 is a peak-current-mode controller for designing wide input-voltage flyback regulators. The MAX17595 offers optimized input thresholds for universal input AC-DC converters and telecom DC-DC (36V to 72V input range) power supplies.
The MAX17509 integrates two 3A internal switch stepdown regulators with programmable features. The device can be configured as two single-phase 3A power supplies or as one dual-phase, single-output 6A power supply.
This document describes a circuit that uses three MAX17541G buck converters and one MAX17504 step-down DC-DC converter. The circuit is arranged so that each buck converter uses the same input with four separate outputs. Each output has a different power specification. The MAX17541G regulator and features are given first, followed by the MAX17504 features.
The MAX15118 high-efficiency, current-mode step-down regulator with integrated power switches operates from 2.7V to 5.5V and delivers up to 18A output current in a small 2mm x 3mm package.
Power over Ethernet (PoE) is a technology that allows network cables to deliver power to a powered device (PD) via power-sourcing equipment (PSE) or midspan, and has many advantages over traditional methods of delivering power.
Due to its simplicity and low cost, the flyback converter is the preferred choice for low-to-medium isolated DC-DC power-conversion applications. However, the use of an optocoupler or an auxiliary winding on the flyback transformer for voltage feedback across the isolation barrier increases the number of components and design complexity.
The MAX668/MAX669 constant-frequency, pulse-width modulating (PWM), current-mode DC-DC controllers are designed for a wide range of DC-DC conversion applications, including step-up, SEPIC, flyback, and isolated-output configurations .
The MAX17690 is a peak current mode, fixed-frequency switching controller specifically designed for the isolated flyback topology operating in Discontinuous Conduction Mode (DCM). The device senses the isolated output voltage directly from the primary-side flyback waveform during the off-time of the primary switch.
The MAX16813 is a highly efficient, high-brightness (HB) LED driver that provides four integrated LED current-sink channels. An integrated current-mode switching controller drives a DC-DC converter that provides the necessary voltage to multiple strings of HB LEDs.
The design provides all the power supply rails and power sequencing necessary to power Xilinx® ZU9/15 Wireless Backhaul power supplies. The MAX15303, MAX20730, MAX17541G and MAX17509 ICs are used to generate all seven rails.
The MAX17506 is a high-efficiency switching regulator that delivers up to 5A load current at output voltages from 0.9V to (0.9 x VIN). The device integrates the highside MOSFET and operates over 4.5V to 60V, making it ideal for on-board point-of load and post-regulation applications.
The MAX15112 high-efficiency, current-mode step-down regulator with integrated power switches operates from 2.7V to 5.5V and delivers up to 12A of output current in a small 2mm x 3mm package. The MAX15112 offers excellent efficiency with skip mode capability at lightload conditions, yet provides unmatched efficiency under heavy load conditions.
The MAXREFDES163# is one of the world’s smallest industrial magnetic sensor solutions that uses a RedRock™ RR120 TMR integrated digital magnetic sensor and the MAX14839, an industrial sensor output.
With dual-isolated RS-485 communication channels for the next generation of ultra-small programmable logic controllers, the MAXREFDES69# meets the data rate and higher voltage needs of industrial control and industrial automation applications, while consuming minimal power and space. This high-performance system features two full-duplex RS-485 transceivers with integrated transformer drivers for efficient and compact power and data isolation.
The MAXREFDES103# is a wrist-worn wearable form factor that demonstrates the high sensitivity and algorithm processing functions for health-sensing applications. This health sensor band platform includes an enclosure and a biometric sensor hub with an embedded heart-rate, SpO2 algorithm (the MAX32664C) which processes PPG signals from the analog-front-end (AFE) sensor (the MAX86141). Algorithm output and raw data can be streamed through Bluetooth® technology to an Android® app or PC GUI for demonstration, evaluation, and customized development.
