AN8014S

Step-down, step-up, or inverting DC-DC converter control IC

■ Overview

Unit: mm

The AN8014S is a single-channel PWM DC-DC

converter control IC.

10.1±0.3

This IC can provide any one output type from

among step-down, step-up and inverting output.

Allowing n-channel power MOSFET direct driv-

ing, the AN8014S is ideal for high-efficiency power

supplies.

■ Features

• Wide operating supply voltage range (3.6 V to 34 V)

(The voltage is limited within a range between 3.6

V and 17 V if it is connected to a step-down volt-

age circuit.)

• On-chip bootstrap circuit (allowing n-channel MOSFET direct driving.)

• On-chip under-voltage lock-out circuit (U.V.L.O.)

• On-chip on/off function (active-high control input, standby current of maximum 5 µA)

• On-chip timer latch short-circuit protection circuit

• Maximum oscillator frequency (500 kHz)

■ Applications

• DC-DC switching power supply
