Switching frequency is pin-selectable to 200kHz or 500kHz — 200kHz keeps MOSFET switching losses low for higher input voltages, while 500kHz shrinks the transformer and output filter magnetics at the cost of higher gate-drive losses. The -40°C to 125°C junction temperature range matches industrial motor-drive and telecom outdoor cabinet environments — no derating needed for ambient temperatures up to 85°C when the thermal pad is properly sinked. ## Synchronous rectification and clock sync — why they matter here Integrated synchronous rectifier driver (SYNC) eliminates the Schottky catch diode on the secondary side — in a 100W isolated converter this drops rectifier losses by roughly 30% compared to a diode-based design. Clock sync input (CLK) allows the controller to lock to an external system clock — useful when multiple converters share a backplane and must avoid beat-frequency noise on the input bus. Soft-start (SS) and frequency-control (RT) pins give the designer programmable inrush current limiting and EMI spreading — the ramp pin lets the compensation network be tuned for the output filter's double-pole response. ## 20-PowerTSSOP — thermal and layout checklist The tube packaging means each IC arrives in a conductive anti-static tube — no reel or tape; the CM's pick-and-place feeder must be set for tube input or the parts are re-taped at the kitting stage. ## Active status and supply posture ROHS3 compliant — no exemption-based lead in solder terminations; passes EU RoHS without a time-limited exemption.
