The OPTIREG™ switcher TLS4120D0EPV33 is a 2.8 MHz synchronous step-down regulator specifically designed for automotive applications. It provides a current capability of 2 A with a fixed 3.3 V output voltage. The device features integrated high-side and low-side power MOSFETs, spread spectrum frequency modulation for improved EMI performance, and an ultra-low quiescent current of 31 µA. It is suitable for battery cranking scenarios due to its wide input voltage range of 3.7 V to 35 V and 100% duty cycle operation.
