AAT1230/1230-1

18V 100mA Step-Up Converter

™

SwitchReg

General Description

Features

The AAT1230/1230-1 is a high frequency, high effi-

ciency boost converter capable of 18V maximum

output voltage. The internal power switch can deliv-

er 100mA load current. It is the ideal power solution

to power OLED, LCD, and CCD applications oper-

ating from a single cell lithium-ion battery.

•

V_INRange: 2.7V to 5.5V

Maximum Output: 18V @ 100mA

True Load Disconnect

Dynamic Voltage Control Options

Hysteretic Control

— No External Compensation Components

— Excellent Load Transient Response

— High Efficiency at Light Load

Up to 2MHz Switching Frequency

Ultra-Small Inductor and Capacitors

Integrated Low R_DS(ON)MOSFET Switches

Up to 85% Efficiency

Hysteretic control provides up to 2MHz switching

frequency and fast response to load transients with

small, low-cost external components. The fully inte-

grated control IC simplifies the design while reduc-

ing the total PCB footprint. The AAT1230/1230-1

offers a true load disconnect feature which isolates

the load from the power source when EN/SET is

pulled low. This eliminates leakage current and

maintains zero voltage at the output while disabled.

•

<1µA Shutdown Current

Integrated Soft Start

Two Turn-On Time Options

— AAT1230: T_SS= 0.35ms

— AAT1230-1: T_SS= 3.5ms

Cycle-by-Cycle Current Limit

Short-Circuit, Over-Temperature Protection

Available in TSOPJW-12 or TDFN34-16

Package

The output voltage can be dynamically set by acti-

vating one of two reference levels (FB1 or FB2)

through the SEL logic pin. Optionally, AnalogicTech’s

•

Simple Serial Control™ (S Cwire™) single wire

interface provides dynamic programmability across

a wide output voltage range through the EN/SET pin.

•

-40°C to +85°C Temperature Range

The AAT1230/1230-1 are available in a Pb-free,

thermally-enhanced 16-pin 3x4mm TDFN low-pro-

file package or a Pb-free 12-pin TSOPJW package.
