This Synchronous Buck Evaluation Board features Microchip's 1A 1.4MHz synchronous buck regulator in two buck converter applications.

The Texas Instruments TPS62020 evaluation module (EVM) for low-power, high-efficiency, step-down converters helps designers evaluate this device. The EVM enables evaluation of different device modes and device performance.

The TPS64202EVM-023 is an evaluation tool for the TPS64202 inductive step-down controller in SOT-23 package which can supply voltages down to 1.2V from a 1.8-V to 6.5-V input.

The TPS40200EVM-001 evaluation module (EVM) uses the TPS40200 nonsynchronous buck converter to provide a resistor-selected 3.3-V output voltage that delivers up to 2.5 A from a 12-V input bus. The EVM operates from a single supply and uses a single P-channel power FET and Schottky diode to produce a low-cost buck converter. The part operates at a 300-kHz clock frequency with provision for externa…

The Texas Instruments TPS62050 and TPS62052 evaluation modules (EVM) for low-power, high-efficiency, step-down converters help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.

The controller utilizes a constant on-time control scheme which eliminates the need for external compensation components, allowing the power supply designer to minimize necessary board space and reduce costs.

The TPS40090EVM−001 multi-phase dc-to-dc converter utilizes the TPS40090 multi-phase controller and UCC27222 predictive gate driver to step down a 12-V input to 1.5V @ 100 A at 420 kHz.

The LM22670 series of regulators are monolithic integrated circuits which provide all of the active functions for a step-down (buck) switching regulator capable of driving up to 3A loads with excellent line and load regulation characteristics. High efficiency (>90%) is obtained through the use of a low ON-resistance N-channel MOSFET.

This evaluation board is an offline, wide-range, VIPer22A-E dual-output power supply with a switching frequency of 60 kHz and is set up for secondary regulation with an optocoupler. One output delivers 5 V at 1 A and a second output delivers 12 V at 0.42 A, making for a total output power of 10 W.

The LM5007 Step down switching regulator features all of the functions needed to implement low cost, efficient, Buck bias regulators.
