1 Features 3 Description

The TPS6108x is a 1.2 MHz/600 kHz fixed-frequency 1• 2.5-V to 6-V Input Voltage Range

boost regulator designed for high integration, which

• Up to 27-V Output Voltage integrates a power switch, an I/O isolation switch, and

• 0.5-A Integrated Switch (TPS61080) a power diode. When a short-circuit condition is

1.3-A Integrated Switch (TPS61081) detected, the isolation switch opens up to disconnect

the output from the input. As a result, the IC protects • 12-V/400-mA and 24-V/170-mA From 5-V Input

itself and the input source from any pin, except VIN, (Typical)

from being shorted to ground. The isolation switch

• Integrated Power Diode also disconnects the output from input during

• 1.2-MHz/600-kHz Selectable Fixed Switching shutdown to prevent any leakage current. Other

Frequency provisions for protection include 0.5 A/1.3 A peak-topeak

overcurrent protection, programmable soft start • Input-to-Output Isolation

(SS), over voltage protection (OVP), thermal

• Short-Circuit Protection shutdown, and under voltage lockout (UVLO).

• Programmable Soft Start

The IC operates from input supplies including single

• Overvoltage Protection Li-ion battery, triple NiMH, and regulated 5 V, such as

• Up to 87% Efficiency USB output. The output can be boosted up to 27 V.

TPS6108x can provide the supply voltages of OLED, • 10-Pin 3-mm × 3-mm QFN Package

TFT-LCD bias, 12-V and 24-V power rails. The output

of TPS6108x can also be configured as a current 2 Applications

source to power up to seven WLEDs in flash light

• 3.3-V to 12-V, 5-V to 12-V, and 24-V Boost applications.
