LT3467/LT3467A

1.1A Step-Up DC/DC

Converter with Integrated Soft-Start

FEATURES

DESCRIPTION

The LT^®3467/LT3467A switching regulators combine a

1.3MHz Switching Frequency (LT3467)

2.1MHz Switching Frequency (LT3467A)

42V, 1.1A switch with a soft-start function. Pin compatible

with the LT1930, its low V_CESATbipolar switch enables the

device to deliver high current outputs in a small footprint.

The LT3467 switches at 1.3MHz, allowing the use of tiny,

low cost and low height inductors and capacitors. The

LT3467A switches at 2.1MHz, allowing the use of even

smaller components. High inrush current at start-up is

eliminated using the programmable soft-start function.

A single external capacitor sets the current ramp rate.

A constant frequency current mode PWM architecture

results in low, predictable output noise that is easy to filter.

Low V

Switch: 330mV at 1.1A

CESAT

High Output Voltage: Up to 40V

Wide Input Range: 2.4V to 16V

Dedicated Soft-Start Pin

5V at 540mA from 3.3V Input (LT3467)

5V at 430mA from 3.3V Input (LT3467A)

12V at 270mA from 5V Input (LT3467)

12V at 260mA from 5V Input (LT3467A)

Uses Small Surface Mount Components

Low Shutdown Current: <1µA

Pin-for-Pin Compatible with the LT1930 and LT1613

Low Profile (1mm) ThinSOT Package

Low Profile (0.75mm) 8-Lead (3mm × 2mm)

DFN Package

AEC-Q100 Qualified for Automotive Applications

The high voltage switch on the LT3467/LT3467A is rated

at 42V, making the devices ideal for boost converters up

to 40V as well as SEPIC and flyback designs. The LT3467

can generate 5V at up to 540mA from a 3.3V supply or 5V

at 450mA from four alkaline cells in a SEPIC design. The

LT3467A can generate 5V at up to 430mA from a 3.3V

supply or 15V at 135mA from a 3.3V supply. The LT3467/

LT3467A are available in a low profile (1mm) 6-lead

SOT-23 package and tiny 3mm × 2mm DFN package.
