Switching frequency is set to either 200 kHz or 500 kHz via an external resistor — the lower frequency reduces switching losses in heavy-load designs; the higher frequency shrinks the transformer and output filter. Clock sync lets multiple controllers share a common timing reference, which suppresses beat-frequency ripple in multi-output supplies. The synchronous rectifier output drives an external SR FET, replacing the freewheeling diode for higher efficiency at the cost of one extra gate-drive channel on the secondary side.","metaTitle":"TI LM5035AMH-1/NOPB Half-Bridge PWM Controller, 105V","metaDescription":"Texas Instruments LM5035AMH-1/NOPB voltage-mode PWM controller, half-bridge topology, 13-105V supply, 200/500kHz, -40 to 125°C.
