LT3470

Micropower Buck Regulator

with Integrated Boost and

Catch Diodes

FEATURES

DESCRIPTIO

TheLT^®3470isamicropowerstep-downDC/DCconverter

that integrates a 300mA power switch, catch diode and

boost diode into a low profile (1mm) ThinSOT^TMpackage.

The LT3470 combines Burst Mode and continuous opera-

tion to allow the use of tiny inductor and capacitors while

providing a low ripple output to loads of up to 200mA.

■

Low Quiescent Current: 26µA at 12V_INto 3.3V_OUT

Integrated Boost and Catch Diodes

Input Range: 4V to 40V

Low Output Ripple: <10mV

<1µA in Shutdown Mode

■

Output Voltage: 1.25V to 16V

200mA Output Current

Hysteretic Mode Control

With its wide input range of 4V to 40V, the LT3470 can

regulate a wide variety of power sources, from 2-cell

Li-Ionbatteriestounregulatedwalltransformersandlead-

acid batteries. Quiescent current in regulation is just 26µA

in a typical application while a zero current shutdown

mode disconnects the load from the input source, simpli-

fying power management in battery-powered systems.

Fast current limiting and hysteretic control protects the

LT3470 and external components against shorted out-

puts, even at 40V input.

– Low Ripple Burst Mode^®Operation at Light Loads

– Continuous Operation at Higher Loads

Solution Size as Small as 50mm²
