TPSM843521 allows high design flexibility with wide supported switching frequency of 200kHz – 2.2MHz set

by the RT/SYNC pin. The device has the option for pulse frequency modulation (PFM), forced continuous

conduction modulation (FCCM) at light load condition, and adjustable soft-start (SS) time / power-good (PG)

indicator with different configuration of the MODE pin.

TPSM843521 provides protection functions including thermal shutdown, input undervoltage lockout, cycle-by-

cycle current limit, and hiccup short-circuit protection. TPSM843521 is available in a 9-pin, 3.3mm × 4.5mm,

QFN package, and the pinout is available for single-layer PCB layout. The junction temperature is specified from

–40°C to 125°C.
