AN8014S集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開關式控制器規(guī)格書PDF中文資料

■ Overview

The AN8014S is a single-channel PWM DC-DC converter control IC.

This IC can provide any one output type from among step-down, step-up and inverting output.

Allowing n-channel power MOSFET direct driving, 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 voltage circuit.)

? Totem pole output circuit: output peak current (±1 A)

? On-chip pulse-by-pulse overcurrent detection and protection circuit

Threshold voltage VCC ? 0.095 V typical

? 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
