LTC3639

High Efficiency, 150V 100mA

Synchronous Step-Down Regulator

FEATURES

DESCRIPTION

The LTC^®3639 is a high efficiency step-down DC/DC

regulator with internal high side and synchronous power

switches that draws only 12μA typical DC supply current

while maintaining a regulated output voltage at no load.

Wide Operating Input Voltage Range: 4V to 150V

Synchronous Operation for Highest Efficiency

Internal High Side and Low Side Power MOSFETs

No Compensation Required

Adjustable 10mA to 100mA Maximum Output

Current

The LTC3639 can supply up to 100mA load current and

features a programmable peak current limit that provides

a simple method for optimizing efficiency and for reduc-

ing output ripple and component size. The LTC3639’s

combination of Burst Mode^®operation, integrated power

switches, low quiescent current, and programmable peak

current limit provides high efficiency over a broad range

of load currents.

Low Dropout Operation: 100% Duty Cycle

Low Quiescent Current: 12µA

Wide Output Range: 0.8V to V

0.8V 1% Feedback Voltage Reference

Precise RUN Pin Threshold

Internal or External Soft-Start

Programmable 1.8V, 3.3V, 5V or Adjustable Output

Few External Components Required

Programmable Input Overvoltage Lockout

Thermally Enhanced High Voltage MSOP Package

AEC-Q100 Qualified for Automotive Applications

Withitswideinputrangeof4Vto150Vandprogrammable

overvoltage lockout, the LTC3639 is a robust regulator

suitedforregulatingfromawidevarietyofpowersources.

Additionally,theLTC3639includesapreciserunthreshold

and soft-start feature to guarantee that the power system

start-up is well-controlled in any environment.
