Fuses are used in many products to protect against possible damage caused by current surges and overcurrents. Traditional fuses used in the automotive space have lower accuracy and longer response times. The TIDA-00795 Automotive Precision Electronic Fuse Reference Design is an alternative to traditional fuses that is more accurate and offers capabilities not found in traditional fuses. This electronic fuse reference design can be used as a building block for implementing a multi-channel electronic fuse box. It can also be used in body control modules (BCM) and electronic control units (ECU).
To meet the increasing demands for isolated Power over Ethernet (PoE) power solutions, Maxim’s power supply experts have developed innovative, isolated, PoE, powered device (PD) power solutions. These isolated PoE power solutions efficiently convert high voltage PoE power into 5V and 12V outputs, respectively. Each design was tested for load and line regulation, as well as efficiency and transient performance. These boards feature a module architecture, with through-hole pins for immediate board placement and accelerated prototyping.
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 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 TIDA-00892 reference design provides a compact solution capable of generating isolated DC power while supporting isolated RS-485 communications. This reference design contains a reinforced digital isolator with integrated power supply and an RS-485 communications transceiver.
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 MAXREFDES1199 demonstrates how to build a lowcost buck DC-DC converter using the step-down converter MAX17244 for 5V DC output applications from a 12V to 32V input. This reference design delivers up to 2.5A at 5V. This design uses a two-layer board and minimizes component count to reduce cost.
The ASL5115EVBSLAV is a slave evaluation board for the MLC ASL5115SHN that works together with the ASL5115EVBMST to evaluate external lighting systems.
This reference design is a dual string LED driver that implements an operational amplifier based circuit which balances the current in two LED rings. The operational amplifier circuit senses current in a reference string and uses feedback from a mirrored string to bias a MOSFET that egulates the current between the strings. The design uses the TPS92692-Q1 multi-topology LED driver in a boost configuration to drive the LEDs. The TPS92692-Q1 features spread spectrum frequency modulation for EMI performance, analog current adjustment and internal PWM dimming. This design includes adjustable linear thermal foldback using the LMT87-Q1 analog temperature sensor, as well as current limiting, in the event the mirrored string fails open circuit. The design also features two brightness modes. One mode is a full brightness mode ('DRL') and the other is a PWM dimming mode ('Position') which reduces brightness.
The MAX17681/MAX17681A is a high-voltage, highefficiency, iso-buck DC-DC converter designed to provide isolated power up to 5W.
The MAXREFDES1049 is a DC-DC buck power supply that delivers up to 3.5A at 5V from a 7.5V to 60V supply voltage. It is designed for equipment that needs to pass the electromagnetic interference (EMI) compliance testing.
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 MAXREFDES1204 is a single-output SEPIC converter reference design developed using the MAX16990 controller. This reference design is rated to operate over a wide input voltage range from 6V to 18V. The design can deliver an output power of 24W at 12V. It is targeted for automotive applications.
The MAX5066 high performance dual buck regulator provides outstanding performance. The reference design in this application note depicts a detailed solution with complete schematic, bill of materials, and load-transient-response scope photos.
A MAX8538 dual synchronous buck controller supplies both +5V and -5V outputs at 3A. One controller operates as a synchronous rectified step-down (buck) converter while the second controller runs a transformer driven inverter. The circuit also features soft start and soft stop .
