FEATURES

GENERAL DESCRIPTION

● Wide Input Voltage from 3V to 5.5V
● 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.
● <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.
● Internal Switch Current Limit : 250 mA Typical dropout voltage is 450mV at 150mA loading for 1.
● High Efficiency at 3.3V to 18V/10mA 8V output, and 100mV at 150mA loading for 3.3V output.
● Dual LDOs With POK The APW7251 has power-on-reset and soft start func-
● High PSRR: 70dB at 1KHz tions to prevent wrong operation and limit the surge cur-
● Low Dropout Voltage: - 450mV at 150mA (LDO1_1.8V) - 100mV at 150mA (LDO2_3.3V) rent during power-on or start-up. It also has thermal shutdown function to protect the device against overtemperature. -...
