TPS61130, TPS61131, TPS61132

SLVS431C – JUNE 2002 – REVISED SEPTEMBER 2015

TPS6113x Synchronous SEPIC and Flyback Converter

With 1.1-A Switch and Integrated LDO

1 Features

3 Description

The TPS6113x devices provide a complete power

supply solution for products powered by either a one-

cell Li-Ion or Li-Polymer, or two- to four-cell Alkaline,

NiCd, or NiMH batteries. The devices can generate

two regulated output voltages. It provides a simple

and efficient buck-boost solution for generating 3.3 V

out of an input voltage that can be both higher and

lower than the output voltage. The converter provides

a maximum output current of at least 300 mA with

supply voltages down to 1.8 V. The implemented

SEPIC converter is based on a fixed frequency,

pulse-width-modulation (PWM) controller using a

synchronous rectifier to obtain maximum efficiency.

The maximum peak current in the SEPIC switch is

limited to a value of 1600 mA.

The converter can be disabled to minimize battery

drain. During shutdown, the load is completely

disconnected from the battery. A low-EMI mode is

implemented to reduce ringing, and in effect, lower

radiated electromagnetic energy when the converter

enters the discontinuous conduction mode. A power

good output at the SEPIC stage provides additional

control of any connected circuits like cascaded power

supply stages, or microprocessors.

The built-in LDO can be used for a second output

voltage derived either from the SEPIC output or

directly from the battery. The output voltage of this

LDO can be programmed by an external resistor

divider or is fixed internally on the chip. The LDO can

be enabled separately, that is, using the power good

of the SEPIC stage. The device is packaged in a 16-

pin VQFN package measuring 4 mm × 4 mm (RSA)

or in a 16-pin TSSOP (PW) package.
