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.
