General Description

The RTQ2131B is a 1A, high-efficiency, current mode

synchronous step-down converter which is optimized for

automotive applications. The device operates with input

voltages from 3V to 36V and is protected from load dump

transients up to 42V, eases input surge protection design.

The device can program the output voltage between 0.8V

to VIN. The peak current mode control with simple external

compensation allows the use of small inductors and

results in fast transient response and good loop stability.

The RTQ2131B provides complete protection functions

such as input under voltage lockout, output under voltage

protection, over current protection, and thermal shutdown.

Cycle-by-cycle current limit provides protection against

shorted outputs and soft-start eliminates input current

surge during start-up. The RTQ2131B is available in

WDFN-10SL 3x3 (Exposed Pad) package.
