It integrates synchronous rectification drive and clock-sync capability. Supply range is 13 V to 105 V; switching frequency is pin-selectable between 200 kHz and 500 kHz. ## Synchronous rectification and clock sync Built-in synchronous rectification drive replaces Schottky catch diodes with MOSFETs. Clock sync lets multiple LM5035ASQ units share a common switching frequency. ## RoHS status and lifecycle The LM5035ASQ is listed as Active in production — no end-of-life notice, no last-time-buy window. It is RoHS non-compliant, which means it cannot be used in assemblies requiring RoHS exemption-free compliance. This is a lead-bearing finish; verify your exemption status before placing it on a RoHS-restricted BOM. The active status and non-RoHS finish together suggest this part is aimed at industrial, military, or high-reliability applications where lead-exempt solder is still accepted.","metaTitle":"LM5035ASQ Half-Bridge PWM Controller, 200-500 kHz, 13-105 V","metaDescription":"LM5035ASQ half-bridge step-up/step-down switching controller. 200 kHz / 500 kHz switching, synchronous rectification, 13 V to 105 V supply.
