AP2002 Datasheet PDF (1.2MHz 1V Low Input Voltage Synch Step-Up Converter)

AP2002 - 1.2MHz 1V Low Input Voltage Synch Step-Up Converter

Description

The AP2002 is synchronous, fixed frequency, step-up DC/DC converters with true cutoff output, delivering high efficiency in a SOT23-6L package.

Capable of supplying 3.6V at 180mA from 1.5V input, the device contains an internal NMOS switch and PMOS synchronous rectifier.

Features

Input voltage rang is 1.1V~5.5V.
Start-up voltage with load is 1V (Typical, when VOUT=3.6V, IOUT=1mA).
Feedback voltage is 500mV.
Max load current is 180mA (when VOUT=3.6V， VIN=1.5V).
High efficiency: Up to 92%.
1.2MHz Constant switching frequency.
True cutoff function: Completely disconnect output from input when EN shutdown device.
0.1µA Shutdown current (Typical).
Protection function: UVLO, OCP, SCP, OTP.
Space saving 6-Pin SOT23-6L package P.

AP2002 Chipown 1.2MHz, and 1V Low Input Voltage, Synch Step-Up Converter with True Cutoff Output General Description The AP2002 is synchronous, fixed frequency, step-up DC/DC converters with true cutoff output, delivering high efficiency in a SOT23-6L package. Capable of supplying 3.6V at 180mA from 1.5V input, the device contains an internal NMOS switch and PMOS synchronous rectifier. A switching frequency of 1.2MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The AP2002 can enter power saving mode at light loads. The AP2002 has true cutoff function, when EN pin input logic low level, the device can disconnect output from input completely, realizing the low shutdown current of under 0.1μA typical from VIN pin.
