The MP28257 is a fully-integrated, synchronous, step-down, switch-mode converter with a programmable frequency.

Product Detail

The MP28257 is a fully-integrated, synchronous, step-down, switch-mode converter with a programmable frequency. It offers a very compact solution that can provide up to 4A of continuous output current over a wide input supply range with excellent load and line regulation, and can operate at high efficiency over a wide output current load range. Constant-on-time control mode provides fast transient response and eases loop stabilization.?Protections include short-circuit protection, over-current protection, over-voltage protection, under-voltage protection, and thermal shut down.? The MP28257 requires a minimal number of readily-available standard external components.?The device is available in a space saving 2mmx3mm QFN12 package that complies with ROHS.
