Vpms2sm Datasheet

The VPM2SM is an integrated circuit (IC) primarily used as an offline LED driver for AC/DC lighting applications. It is designed for high efficiency and minimal external component count, making it a popular choice for compact LED bulbs and power supplies.  Key Technical Specifications 

15. Example application notes

• Sequenced 3-rail SoC power-up: enable LDO1 → wait 5 ms → enable LDO2 → wait 2 ms → enable core rail; hold reset until all PGs asserted and 50 ms stabilization.
• Battery-powered device: use undervoltage threshold to gracefully shut down high-power modules and save state before complete power loss. Practical tip: Always add a capacitor-backed small microcontroller energy reservoir (supercap or small battery backup) if you need to save state reliably during imminent power loss.
