MP1496
High-Efficiency, 2A, 16V, 500kHz
Synchronous, Step-Down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP1496 is a high-frequency, synchronous,
rectified, step-down, switch-mode converter
with built-in power MOSFETs. It offers a very
compact solution to achieve a 2A continuous
output current with excellent load and line
regulation over a wide input supply range. The
MP1496 has synchronous mode operation for
higher efficiency over the output-current–load
range.
Current-mode operation provides a fast
transient response and eases loop stabilization.
Protective
features
include
over-current
protection and thermal shut down and external
SS control.
The MP1496 requires a minimal number of
readily-available standard external components,
and is available in a space-saving 8-pin
TSOT23 package.
