描述 Description

The TS30041 (1A) and TS30042 (2A) are DC/DC synchronous

switching regulators with fully integrated power switches,

internal compensation, and full fault protection. The switching

frequency of 1MHz enables the use of small ! lter components

resulting in minimal board space and reduced BOM costs.

The TS30041/42 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 TS30041/42 integrates a wide range of protection circuitry

including input supply under-voltage lockout, output voltage

soft start, current limit, and thermal shutdown.

The TS30041/42 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
