Datasheet – MAP7160
600mA Step-Down Converter with Auto Fast Discharge Function
General Description
The MAP7160 is a 2MHz high efficiency step-down
converter with input voltage of 2.7V to 5.5V
Output Voltage has as low as 0.6V. The MAP7160 has
a high efficiency and Low ripple architecture.
The MAP7160 is programmable with external
feedback resistors and it has a low 35uA no load
quiescent current.
The MAP7160 operates as 2MHz switching frequency.
The MAP7160 is designed to maintain high efficiency
at operating range. And The MAP7160 has an output
auto discharge function. When Output voltage is
disabled, it enables the device to quickly output
discharge.

Note 1: Stress beyond the maximum ratings listed above may incur permanent damage to the device. Operating above the
recommended conditions for extended time may stress the device and affect device reliability. Also the device may not operate
normally above the recommended operating conditions. These are stress ratings only.
Note 2: Guaranteed by design; not test in production.

Over Current Protection
For overload conditions, the peak input current is limit-
ed. To minimize power dissipation and stresses under
current limit and short-circuit conditions, switching is
terminated after entering current limit for a series of
pulses. Switching is terminated for seven consecutive
clock cycles after a current limit has been sensed for a
series of four consecutive clock cycles.
Over Temperature Protection
Thermal protection completely disables switching when
internal dissipation becomes excessive. The junction
over-temperature threshold is 140°C with 15°C of hys-
teresis. Once an over-temperature or over-current fault
conditions is removed, the output voltage automatically
recovers.
