EV2908A-F-02A

Wide Input, Current Mode Synchronous Step-Down Controller Evaluation Board

Datasheet

Description

The EV2908A-F-02A is an evaluation board for MP2908A/MPQ2908A, a high voltage, synchronous step-down switching regulator controller that can directly step-down voltages from up to 60V.

It uses PWM current control architecture with accurate cycle-by-cycle current limiting and is capable of driving dual N-channel MOSFETs.

Advanced asynchronous mode (AAM) enables non-synchronous operation to optimize light-load efficiency.

The operating frequency of the MP2908A/MPQ2908A can be programmed by an external resistor or synchronized to an external clock for noise-sensitive applications. Full protection features include precision output over-voltage protection (OVP), output over-current protection (OCP), and thermal shutdown.

The EV2908A-F-02A is assembled and tested with TSSOP20-EP package.
