DESCRIPTION
The MPM3834C is synchronous, step-down
power module with an integrated inductor. The
MPM3834C achieves 3A of continuous output
current (IOUT) from a 2.75V to 6V input voltage
(VIN) range, with excellent load and line
regulation. The MPM3834C works in forced
continuous conduction mode (FCCM) and has a
small output voltage (VOUT) ripple with one
output capacitor. This makes the device wellsuited
for optical modules, FPGA, ASIC, and
other applications requiring low ripple noise and
a small PCB area.
VOUT can be regulated to be as low as 0.6V.
Only FB resistors, input capacitors, and output
capacitors are required to complete the design.
Constant-on-time control (COT) provides fast
transient response, high efficiency, and easy
loop stabilization.
Full protection features include cycle-by-cycle
current limiting, short-circuit protection (SCP)
with hiccup mode, and thermal shutdown.
The MPM3834C requires a minimal number of
readily available, standard external
components. It is available in an ultra-small
ECLGA-14 (2.5mmx2.5mmx1.2mm) package.
