High Efficiency 1A/2A Current-Mode Synchronous Buck Converter, 2.2MHz

Topology: Buck
Input Voltage (min.): 4.50 V
Input Voltage (max.): 40.00 V
Output 1: 5.00 V / 1.000 A


The TS30041Q (1A) and TS30042Q (2A) are DC/DC synchronousswitching regulators with fully integrated power switches,internal compensation and full fault protection. The switchingfrequency of 2.2 MHz enables the use of small filter componentsresulting in minimal board space and reduced BOM costs.The TS30041Q/42Q utilizes current mode feedback in normalregulation 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 protectioncircuitry including input supply under-voltage lockout, outputvoltage soft start, current limit and thermal shutdown.The TS30041Q/42Q includes supervisory reporting throughthe PG (Power Good) open drain output to interface othercomponents in the system.
