TPS61093-Q1 Low Input Boost Converter

With Integrated Power Diode and Input/Output Isolation

1 Features

3 Description

The TPS61093-Q1 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. This disconnection protects

the IC and the input supply. The isolation switch also

disconnects the output from the input during shut

down to minimize leakage current. When the IC is

shutdown, 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).
