The Future of Analog IC Technology
DESCRIPTION
The MP2908A is a high-voltage, synchronous
step-down controller that directly steps down
voltages from up to 60V. The MP2908A uses
PWM current control architecture with accurate
cycle-by-cycle current limiting and is capable of
driving dual N-channel MOSFETs.
Advanced asynchronous mode (AAM) enables
non-synchronous operation to optimize light-
load efficiency.
The operating frequency of the MP2908A can
be programmed by an external resistor or
synchronized to an external clock for noise-
sensitive applications. Full protection features
include precision output over-voltage protection
(OVP), output over-current protection (OCP),
and thermal shutdown.
The MP2908A is available in TSSOP20-EP and
QFN-20 (3mmx4mm) packages.
