♠ TPS785-Q1 Automotive, 1-A, High-PSRR Low-Dropout Voltage Regulator With High Accuracy and Enable

The LMR33620-Q1 automotive-qualified regulator is an easy-to-use, synchronous, step-down DC/DC converter that delivers best-in-class efficiency for rugged applications.

The LMR33620-Q1 drives up to 2 A of load current from an input of up to 36 V.

The LMR33620-Q1 provides high light load efficiency and output accuracy in a very small solution size. Features such as a power-good flag and precision enable provide both flexible and easy-touse solutions for a wide range of applications.

The LMR33620-Q1 automatically folds back frequency at light load to improve efficiency. Integration eliminates most external components and provides a pinout designed for simple PCB layout. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limit, and hiccup short-circuit protection.

The LMR33620-Q1 is available in a 12-pin 3 mm × 2 mm next generation VQFN package with wettable flanks.
