SMALL PACKAGE PFM CONTROL

STEP-UP DC/DC CONVERTER

CE8301 Series

Introduction

The CE8301 Series is a CMOS PFM-control

step-up switching DC/DC converter that

mainly consists of a reference voltage

source, an oscillator, and a comparator. The

PFM controller allows the duty ratio to be

automatically switched according to the load

(light load: 50%, high output current: 75%),

enabling products with a low ripple over a

wide range, high efficiency, and high output

current. With the CE8301 Series, a step-up

switching

DC/DC

converter

can

be

configured by using an external coil,

capacitor, and diode. The built-in MOS FET is

turned off by a protection circuit when the

voltage at the LX pin exceeds the limit to

prevent it from being damaged. This feature,

along with the mini package and low current

consumption, makes the CE8301 Series

ideal for applications such as the power

supply unit of portable equipment.

Applications

• Power supply for portable equipment such

as digital cameras, electronic notebooks, and

PDAs

• Power supply for audio equipment such as

portable CD/MD players

• Constant voltage power supply for cameras,

video equipment, and communications

equipment

• Power supply for microcomputers

Features

• Low voltage operation: Startup at 0.9 V

min. (IOUT = 1 mA) guaranteed

• Duty ratio: 66/78%, builtin auto switching

type PFM controller

• External parts: Coil, capacitor, diode

• Output voltage: Settable to between 1.8

to 6.5 V in 0.1 V steps

• Accuracy of ±2%

• High efficiency：85%（typ.）

• Standard function (product type A)

• Shutdown function (product type C、D)

• Output voltage Adjustable type (product

type E、F)

• External transistor type available

(product type B、 E、F)
