1 Features

• Input voltage range: 0.5 V to 5.5 V

• 0.7-V minimum input voltage for start-up

• Input operating voltage down to 150 mV with

signal VIN > 0.7 V

• Output voltage range: 1.8-V to 5.5-V VSEL pin

select output voltage

• Average input current limit: 5 mA; 25 mA; 50 mA;

100 mA; 250 mA, 500 mA, 1.2 A, 1.9A (different

versions)

• 95-nA typical quiescent current from VOUT

• 60-nA typical shutdown current from VIN and SW

• Up to 91 efficiency at VIN = 3.6 V, VOUT = 5 V,

and IOUT =10 μA

• Up to 94 efficiency at VIN = 3.6 V, VOUT = 5 V,

and IOUT =200 mA

• Fast transient performance: setting time ~8 μs at

VIN = 3.6 V, VOUT = 5 V, IOUT = 0 A -> 200 mA

3 Description

The TPS61299 is a synchronous boost converter with

95-nA ultra-low quiescent current and average input

current limit. The device provides a power solution

for portable equipment with alkaline battery and coin

cell battery. This device has high efficiency under

light-load condition to achieve long operation time

and average input current limit can avoid battery

discharging with high current.

The TPS61299 has wide input voltage range from 0.5

V to 5.5 V and output voltage range from 1.8 V to

5.5 V. The device has different versions for average

input current limit from 5 mA to 1.9 A. The TPS61299

with 1.2-A current limit can support up to 500-mA

output current from 3-V to 5-V conversion and achieve

approximately 94 efficiency at 200-mA load.

The TPS61299 has optional fast-load transient

performance at output voltage is 4.5 V, 5 V or 5.5 V.

In fast-load transient, the typical setting time is 8 μs

when output current transient from 0 A to 200 mA.

The TPS61299 supports optional force pass through

or true shutdown function when it is disabled, which is

flexible for always-on system.

The TPS61299 offers a very small solution size with

6-ball 1.2-mm x 0.8-mm WCSP package and 6-pin

1.6-mm x 0.6-mm SOT563 package.
