MP28257 4A, Fast Transient, 4.2V-to-20V Input Synchronous Step-Down Converter The Future of Analog IC Technology R DESCRIPTION The MP28257 is a fully-integrated, synchronous, O step-down, switch-mode converter with a programmable frequency. It offers a very F compact solution that can provide up to 4A of continuous output current over a wide input supply range with excellent load and line D regulation, and can operate at high efficiency over a wide output current load range. E Constant-on-time control mode provides fast transient response and eases loop stabilization. D Protections include short-circuit protection, N S 4 over-current protection, over-voltage protection, under-voltage protection, and thermal shut E N 8 down.
