The TPSM843521 is a high-efficiency, high-power density, and easy-to-use, synchronous buck power module with high design flexibility. With operating input voltage ranging from 3.8V to 18V, the TPSM843521 is designed for systems powered from 5V, 12V power-bus rails. The device supports up to 5A continuous output current and 98% maximum duty cycle.

TPSM843521 uses fixed frequency peak current control with internal compensation for fast transient response and good line and load regulation. With the optimized internal loop compensation, the device eliminates the need for external compensation over a wide output voltage range and switching frequency.

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.
