6V, 6A, High-Efficiency,
Synchronous Step-Down Converter
The MP2176 is a monolithic, step-down, switch-
mode converter with internal power MOSFETs
that can achieve up to 6A of continuous output
current from a 1.5V to 6V input voltage with
excellent load and line regulation. The output
voltage can be regulated as low as 0.61V.
Constant-on-time (COT) control provides fast
transient response and eases loop stabilization.
Fault condition protections include cycle-by-
cycle current limiting and thermal shutdown.
The operating frequency is programmed by an
external resistor and is compensated for
variations in VIN.
Full protection features, including over-current
protection (OCP), short-circuit protection (SCP),
over-voltage protection (OVP), under-voltage
protection (UVP), and over-temperature
protection (OTP), are provided by internal
The MP2176 requires a minimal number of
readily available, standard, external
components and is available in a QFN-14
