TS30111
Version 1.0
High Efficiency 700mA Current-Mode Synchronous Buck DC/DC
Converter, 1MHz
DESCRIPTION
The TS30111 is a DC/DC synchronous switching
regulator with fully integrated power switches,
internal compensation, and full fault protection. The
switching frequency of 1MHz enables the use of
small filter components resulting in minimal board
space and reduced BOM costs.
The TS30111 utilizes current mode feedback in
normal regulation PWM mode. When the regulator
is placed in standby (EN is low), the device draws
less than 10uA quiescent current.
The TS30111 integrates a wide range of protection
circuitry including input supply under-voltage
lockout, output voltage soft start, current limit, and
thermal shutdown.
The TS30111 includes supervisory reporting through
the PG (Power Good) open drain output to interface
other components in the system.
