AS3713
Quad Buck High Current PMIC without
Charger
The AS3713 is a compact System PMU with booster and back
light driver. The device offers advanced power management
functions. All necessary ICs and peripherals in a battery
powered mobile device are supplied by the AS3713. It features
3 DC/DC buck converters as well as 8 low noise LDOs. The
different regulated supply voltages are programmable via the
serial control interface. 4MHz operation with 1μH coils are
reducing cost and PCB space. AS3713 further features a DC/DC
buck controller which is ideal to support processor core
currents up to 3A.
The two step-up converter generate voltages for e.g.the
backlight, classD amplifier, USB host support or LCD display
supply. Both constant voltage (for e.g. OLED supply) as well as
constant current (white LED backlight) operations with three
current sinks are possible. An internal voltage protection is
limiting the output voltage in the case of external component
failures.
The single supply voltage may vary from 2.7V to 5.5V.
