MP28257
DESCRIPTION
The MP28257 is a fully-integrated, synchronous,
O step-down, switch-mode converter with a programmable frequency. It offers a very
F pact 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. M IG 3 The MP28257 requires a minimal number of readily-available standard external ponents.
2 The device is available in a space saving M S P 2mmx3mm QFN12 package that plies with O E M ROHS.
