APW7251/A Boost and Dual LDOs with POK Features General Description • Wide Input Voltage from 3V to 5.5V The APW7251 contains a PWM Boost converter, a 1.8V • Built-in Soft-start linear regulator and a 3.3V linear regulator. • B oo s t Co n ve r te r F ix e d Out p ut Vo lt a ge : The PWM boost converter is a high frequency step-up APW7251:13.5V DC/DC converter. Its output voltage is set by an internal APW7251A:12.3V feedback divider at 13.5V and 12.3V. • <1uA Quiescent Current During Shutdown • Boost Converter in PFM Mode The regulator is a P-channel low dropout linear regulator with POK which needs only one input voltage from 3 to 5. 5V, and delivers current up to 10mA to set output voltage.
