LT3653

1.2A, HV Input Regulator

with Output Current Limit for

Battery Charger Applications

DESCRIPTION

FEATURES

TheLT^®3653isamonolithiccurrentmodePWMstep-down

regulatorwithprogrammableoutputcurrentlimit.Typically,

it is used with battery charger power path controllers to

pre-regulate the output and optimize the battery charger

efﬁciency. Output current limit provides accurate control

over system power dissipation.

Wide Input Range:

– Operation from 7.5V to 30V

– Overvoltage Lockout Protects Circuit Through 60V

Transients

Operates with LTC Bat-Track™ Li-Ion Battery

The wide operating input voltage range of 7.5V to 30V

suits the LT3653 to a variety of input sources, including

unregulated 12V wall adapters, 24V industrial supplies,

Firewire and automotive power. Input overvoltage protec-

tion allows the LT3653 to handle 60V input transients.

discharge during an open or shorted input.

Battery Powered Equipment

The HVOK pin indicates that the internal bias supplies

are present and no faults have occurred (i.e., overtem-

perature and input overvoltage and undervoltage). The

LT3653 includes a 1.5MHz frequency oscillator, internal

compensation,andaninternalboostdiodetominimizethe

number of external components. The LT3653 is available

in an 8-lead (2mm × 3mm) package with exposed pads

for low thermal resistance.
