3 Description

The TPS61093 is a 1.2-MHz, fixed-frequency boost

converter designed for high integration and high

reliability. The IC integrates a 20-V power switch,

input/output isolation switch, and power diode. When

the output current exceeds the overload limit, the

isolation switch of the IC opens up to disconnect the

output from the input, thus protecting the IC and the

input supply. The isolation switch also disconnects

the output from the input during shutdown to minimize

leakage current. When the IC is shut down, the

output capacitor is discharged to a low voltage level

by internal diodes. Other protection features include

1.1-A peak overcurrent protection (OCP) at each

cycle, output overvoltage protection (OVP), thermal

shutdown, and undervoltage lockout (UVLO).

With its 1.6-V minimum input voltage, the IC can be

powered by two alkaline batteries, a single Li-ion

battery, or 3.3-V and 5-V regulated supply. The

output can be boosted up to 17 V. The TPS61093 is

available in 2.5 mm × 2.5 mm VSON package with

thermal pad.
