: It is often grouped with similar variants like the VPMS2RT or VPMS3RT, which share the same architectural focus on voltage regulation and circuit protection. Where to Find Technical Documentation
The VPMS2SM is a highly integrated power solution that functions as both a DC-DC converter and a PMIC. It is specifically engineered to generate all the necessary voltages for a modern TV's main board and T-con board. Key voltage rails associated with the VPMS2SM and the wider system include:
The VPMS2SM datasheet highlights its versatility across varying electrical environments: 4.5V to 36V Switching Frequency: 500kHz Package Type: QFN-72 (8x8x0.9 mm) Interfaces: Native support for SPI, I²C, and UART Max Clock Frequency: 120 MHz Thermal Resistance ( θJAtheta sub cap J cap A end-sub ): 40 °C/W Key Features and Performance vpms2sm datasheet
