FEATURES
Buck PWM with Internal PMOS 4.5V to 15.0V Input Voltage Range Max. 2A Output Current Under-Voltage Lockout (UVLO) Protection Internal Short Circuit and Thermal Protection Internal Soft-Start Fixed Switching Frequency (380kHz / 47kHz) 2 µA Shutdown Current SOP- 8 Package PIN CONFIGURATION GENERAL DESCRIPTION
The AAT1346A/B/C contains one buck current mode PWM with internal PMOS. In addition, a digital soft-start is also included to prevent inrush current at startup. AAT1346A/B/C comes with a fixed 380kHz oscillator, however, when the feedback voltage is lower than 0.7V, the switching frequency changes to 47kHz and returns to 380kHz after the short-circuit is released.
