FAN5340

Four Channel Controller for Switching Regulator

Features

Description

• 2.5V to 7.5V Input Voltage Range

The FAN5340 is a ﬂexible voltage-mode four-channel

switching regulator, consuming very low quiescent current.

The four channels can be conﬁgured to operate either as

buck, boost, sepic, or inverting converters. Mode selection is

achieved by connecting the SEL pin to V_IN, GND, or left

ﬂoating for boost/sepic, inverter and buck operation respec-

tively. The controller outputs are suitable to drive external

bipolar transistors, P-ch or N-ch MOSFET.

• Four Independent PWM/PFM Channels

• Four Independent Enable Controls

• Four Independent Built-in Soft Start Functions

• Drives MOSFET or BIPOLAR Power Switch

• Channels are Conﬁgurable as Buck, Boost, Inverting, or

Sepic Converters

• 500µA Quiescent Current (Typ.)

• Supply Current in Off Mode is less than 3µA

• 500kHz Clock

• Independent On/Off Control for Each Channel

• Short Circuit Protection for Buck and Inverter

The device has very low quiescent current, which makes it

ideally suitable for portable electronic equipment.

The FAN5340 is available in a 20-lead TSSOP package.

• Digital Still Cameras

• PDAs

• Handheld Equipment
