AP1510

PWM Control 3A Step-Down Converter

Features

General Description

- Input voltage: 3.6V to 23V.

AP1510 consists of step-down switching regulator

with PWM control. These devices include a reference

voltage source, oscillation circuit, error amplifier,

internal PMOS and etc.

- Output voltage: 0.8V to V_CC

- Duty ratio: 0% to 100% PWM control

- Oscillation frequency: 300KHz typ.

- Soft-start, Current limit, Enable function

- Thermal Shutdown function

AP1510 provides low-ripple power, high efficiency,

and excellent transient characteristics. The PWM

control circuit is able to very the duty ratio linearly

from 0 up to 100%. This converter also contains an

error amplifier circuit as well as a soft-start circuit that

prevents overshoot at startup. An enable function,

an over current protect function and a short circuit

protect function are built inside, and when OCP or

SCP happens, the operation frequency will be

reduced from 300KHz to 30KHz. Also, an internal

compensation block is built in to minimum external

component count.

- Built-in internal SW P-channel MOS

- SOP-8L Pb-Free Package.

Applications

- PC Motherboard

- LCD Monitor

- Graphic Card

- DVD-Video Player

- Telecom Equipment

- ADSL Modem

- Printer and other Peripheral Equipment

- Microprocessor core supply

- Networking power supply

With the addition of an internal P-channel Power MOS,

a coil, capacitors, and a diode connected externally,

these ICs can function as step-down switching

regulators. They serve as ideal power supply units for

portable devices when coupled with the SOP–8L

mini-package, providing such outstanding features as

low current consumption. Since this converter can

accommodate an input voltage of up to 23V, it is also

ideal when operating via an AC adapter.
