FUNCTION
Error-Amplifier Output. COMP can be used for soft-start.
Error-Amplifier Inverting Input
Input to the PWM Comparator and Overcurrent Protection Comparator. The current-sense signal is
compared to a signal proportional to the error-amplifier output voltage.
Timing Resistor and Capacitor Connection. A resistor R T from R T /C T to VREF and capacitor C T from
R T /C T to GND set the oscillator frequency.
Power-Supply Ground. Place the V CC and VREF bypass capacitors close to the IC to minimize
ground loops.
MOSFET Driver Output. OUT connects to the gate of the external n-channel MOSFET.
Power-Supply Input for MAX5070. Bypass V CC to GND with a 0.1μF ceramic capacitor or a parallel
combination of a 0.1μF and a higher value ceramic capacitor.
5V Reference Output. Bypass VREF to GND with a 0.1μF ceramic capacitor or a parallel combination
of a 0.1μF and a higher value ceramic capacitor.
