A5973D is a lower -voltage single -chip power switch voltage regulator with a minimum switch current limit of 2.5A, so it can transport DC current greater than 2A according to the application conditions. The output voltage can be set between 1.235V and 35V. The realization of high -current levels also benefits from the exposed framework of SO8 packaging, which can reduce the Thth (JA) to about 40 ° C/W. The device uses an internal P channel D-MOS transistor (the typical RDSON is 250MΩ) as the switch component to minimize the size of the external component. The internal oscillator fix the switching frequency to 250kHz. The minimum input voltage is only 4V, which is especially suitable for 5V bus. The pulse current limit and internal frequency modulation provides effective constant current short circuit protection. The pulse current limit and internal frequency modulation provides effective constant current short circuit protection.
