LT1613

1.4MHz, Sing le Ce ll DC/ DC

Co nve rte r in 5-Le a d SOT-23

DESCRIPTIO

FEATURES

■

Uses Tiny Capacitors and Inductor

Internally Compensated

Fixed Frequency 1.4MHz Operation

The LT^®1613 is the industry’s first 5-lead SOT-23 current

mode DC/DC converter. Intended for small, low power

applications, it operates from an input voltage as low as

1.1V and switches at 1.4MHz, allowing the use of tiny, low

cost capacitors and inductors 2mm or less in height. Its

small size and high switching frequency enables the

complete DC/DC converter function to take up less than

0.2 square inches of PC board area. Multiple output power

supplies can now use a separate regulator for each output

voltage, replacing cumbersome quasi-regulated ap-

proaches using a single regulator and a custom trans-

former.

■

Operates with V as Low as 1.1V

■

3V at 30mA from a Single Cell

5V at 200mA from 3.3V Input

15V at 60mA from Four Alkaline Cells

High Output Voltage: Up to 34V

Low Shutdown Current: <1µA

Low V_CESATSwitch: 300mV at 300mA

Tiny 5-Lead SOT-23 Package

A constant frequency, internally compensated current

mode PWM architecture results in low, predictable output

noise that is easy to filter. The high voltage switch on the

LT1613 is rated at 36V, making the device ideal for boost

converters up to 34V as well as for Single-Ended Primary

Inductance Converter (SEPIC) and flyback designs. The

device can generate 5V at up to 200mA from a 3.3V supply

or 5V at 175mA from four alkaline cells in a SEPIC design.
