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.
