TLS4125D0EPV50XUMA1

TLS4125D0EPV50XUMA1 OPTIREG™ switcher is a 2.8MHz synchronous step-down regulator specially designed for automotive applications. The device has a current capability of 2.5A, fixed 5V output voltage and a feedback voltage accuracy of ±1.5% in PWM mode. The integrated power stages, soft-start feature and integrated compensation network reduce the required amount of external components and thus system costs and board space. The wide input voltage range and a 100% duty cycle operation mode make the device suitable for battery-cranking scenarios in automotive applications. The wide switching frequency range allows the selection of appropriate coils and capacitors. The switching frequency can be synchronized to an external clock signal. Potential applications include body, ADAS, infotainment, telematics, and navigation.
