Function
External power switch driver with 1.0 A peak capability. Rail to rail output occurs when the capacitive load is
between 470 pF and 10 nF.
Current sense comparator input.
Bidirectional synchronization. Locks to highest frequency.
PWM ramp.
Undervoltage protection monitor.
Overvoltage protection monitor.
Timing resistor R T and capacitor C T determine oscillator frequency and maximum duty cycle, D MAX .
Voltage at this pin sets pulse ? by ? pulse overcurrent threshold.
Feedback voltage input. Connected to the error amplifier inverting input.
Error amplifier output.
Charging external capacitor restricts error amplifier output voltage during the power up or fault conditions.
Logic ground.
3.3 V reference voltage output. Decoupling capacitor can be selected from 0.01 m F to 10 m F.
Logic supply voltage.
Output power stage ground.
Output power stage supply voltage.
