DESCRIPTION
MAS9250 is a step-down switching regulator with
an internal main PMOS switch and a synchronous
NMOS switch. No external Schottky diode is
required. MAS9250 uses constant frequency Pulse
Width Modulation (PWM) current mode architecture
to control the output voltage. As a default the
switching frequency is set internally to 550 kHz.
However, it can be adjusted up to 2 MHz by
applying an external resistor between FSR input
and ground or by applying an external frequency
from 400 kHz to 2 MHz to SYNC/M1 input.
Connecting SYNC/M1 to V
IN
enables MAS9250 to
switch automatically to the Pulsed Frequency Mode
(PFM) instead of PWM mode at light loads. When
SYNC/M1 is connected to ground, MAS9250 works
in PWM mode also at light loads thus preventing
low frequency ripple from interfering other circuitry
in the application.
In order to save power the device goes into sleep
mode when the regulator is disabled.
