Semtech TS30042Q

Description

The TS30041Q (1A) and TS30042Q (2A) are DC/DC synchronous switching regulators with fully integrated power switches, internal compensation and full fault protection. The switching frequency of 2.2 MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs. The TS30041Q/42Q 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 TS30041Q/42Q integrates a wide range of protection circuitry including input supply under-voltage lockout, output voltage soft start, current limit and thermal shutdown. The TS30041Q/42Q includes supervisory reporting through the PG (Power Good) open drain output to interface other components in the system.
