MAXREFDES116# is an efficient, active clamp topology, isolated power supply design with 24V input, and a 5V output at 40W of power (8A). The design features the MAX17599, an active clamp, current-mode PWM controller optimized for industrial supplies. This entire circuit fits on a 20mm x 70mm board.
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. It contains a built-in gate driver for an external n-channel MOSFET. The MAX17595 houses an internal error amplifier with 1% accurate reference, eliminating the need for an external reference.
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 MAX17509 integrates two internal switch step-down regulators with programmable features. The device can be configured as two single-phase independent power supplies or as a dual-phase, single-output power supply. The device operates from 4.5V to 16V input and generates independently adjustable output voltage in the ranges of 0.904V to 3.782V and 4.756V to 5.048V, with ±2% system accuracy. The MAX17509 provides maximum flexibility to end-users by allowing them to choose multiple programmable options by connecting resistors to the configuration pins. Two key highlights of the device are the self-configured compensation for any output voltage and the ability to program the slew rate of LX switching nodes to mitigate noise concerns. Noise-sensitive applications, such as high-speed multigigabit transceivers in FPGAs, RF, and audio, benefit from this unique slew-rate control. SYNC input is provided for synchronized operation of multiple devices with system clocks.
The MAX5971B is a single-port power controller designed for use in IEEE 802.3af/at-compliant power-sourcing equipment (PSE). This reference design provides a detailed technical guide to designing the MAX5971B PSE controller for DC-disconnect.
The MAXREFDES1171 uses Maxim® low-power chips for power grid fault indicators based on the low-power Arm® Cortex®-M4 processor.
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. The MAXREFDES1149 reference design is a 36V~57V input to 12V/1A output flyback PoE PD power module to be used in Ethernet equipment that needs the 12V power supply to be isolated from the primary Ethernet power.
