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.
Applications
• On-card switching regulators
• Set-top box, DVD, LCD, LED supply
• Industrial power supplies
