3 Description

The TPS61088 is a high power density, fully

integrated synchronous boost converter with a 11-mΩ

power switch and a 13-mΩ rectifier switch to provide

a high efficiency and small size solution in portable

systems. The TPS61088 has wide input voltage

range from 2.7 V to 12 V to support applications with

single cell or two cell Lithium batteries. The device

has 10-A switch current capability and is capable of

providing an output voltage up to 12.6 V.

The TPS61088 uses adaptive constant off-time peak

current control topology to regulate the output

voltage. In moderate to heavy load condition, the

TPS61088 works in the pulse width modulation

(PWM) mode. In light load condition, the device has

two operation modes selected by the MODE pin. One

is the pulse frequency modulation (PFM) mode to

improve the efficiency and another one is the forced

PWM mode to avoid application problems caused by

low switching frequency. The switching frequency in

the PWM mode is adjustable ranging from 200 kHz to

2.2 MHz by an external resistor. The TPS61088 also

implements a programmable soft-start function and

an adjustable switching peak current limit function. In

addition, the device provides 13.2-V output

overvoltage protection, cycle-by-cycle overcurrent

protection, and thermal shutdown protection.

The TPS61088 is available in a 4.50-mm × 3.50-mm

20-pin VQFN package.
