FP5003 High Frequency PWM Controller With Short Circuit Restart General Description The FP5003, a high performance monolithic IC, includes adjustable frequency oscillator, error amplifier for pulse width modulation (PWM) control, 1.0V precision voltage reference, under-voltage lockout circuit (UVLO), variable pulse duty control (DTC) circuit and programmable auto-restart timer for short circuit shutdown protection (SCSAR). Built-in totem-pole transistors pair drives MOS directly at high frequency operation with high efficiency. It is very easy to design a DC-DC converter using a few external components. The typical application example is shown below: Features  Wide Operating Voltage Range:3.
