Free Datasheet http://www.datasheetlist.com/ Synchronous Single Buck PWM Controller Features ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ ‹ CAT7581 General Description The CAT7581 is a voltage mode PWM controller designed to operate from a 4.5 V to 13.2 V supply and produce an output voltage as low as 0.8 V. This 8-pin device provides an optimal level of integration to reduce size and cost of the power supply. The CAT7581 has a fixed 300 kHz oscillator and soft-start function. The CAT7581 provides a 1.5A floating gate driver design to drive N-Channel MOSFETs in a synchronous configuration. The Adaptive non overlap circuitry reduces switching losses by preventing simultaneous conduction of both outputs. Protection features include input Under Voltage LockOut (UVLO), output Under Voltage Protection (UVP), output Over Voltage Protection (OVP), and Over Current Protection (OCP). The OCP monitors the voltage drop across the RDS(ON) of the low side MOSFETs, eliminating the need of a current sensing resistor. The CAT7581 is available in an 8-pin SOIC package. Input Voltage Range from 4.5 V to 13.2 V...
