LTC3532

Micropower Synchronous

Buck-Boost DC/DC Converter

DESCRIPTIO

FEATURES

The LTC^®3532 is a high efﬁciency, ﬁxed frequency, buck-

boost DC/DC converter that operates from input voltages

above, below or equal to the output voltage. The topology

incorporated in the IC provides a continuous transfer

function through all operating modes, making the product

ideal for single lithium-ion, multicell alkaline or NiMH ap-

plications where the output voltage is within the battery

voltage range.

■

Single Inductor

■

Regulated Output with Input Voltages Above, Below

or Equal to the Output

■

Wide V Range: 2.4V to 5.5V

■

OUT

Range: 2.4V to 5.25V

Up to 500mA Peak Output Current

Synchronous Rectiﬁcation: Up to 95% Efﬁciency

Manual or Programmable Automatic Burst Mode^®

Operation

Output Disconnect in Shutdown

Programmable Oscillator: 300kHz to 2MHz

Pin Compatible with LTC3440

The device includes two 0.36Ω N-channel MOSFET

switches and two 0.42Ω P-channel switches. Switching

frequencies up to 2MHz are programmed with an external

resistor. Quiescent current is only 35μA in Burst Mode

operation, maximizing battery life in portable applica-

tions. Automatic Burst Mode operation allows the user

to program the load current for Burst Mode operation or

to control it manually.
