Error amplifier
Vref overvoltage protection (OVP)
Features
Wide supply voltage range: 3.9 V to 40 V
*
Maximum operating frequency: 600 kHz
Able to drive a power MOS FET (±1 A maximum peak current) by the built-in totem-pole gate pre-
driver circuit
Can operate in synchronization with an external pulse signal, or with another controller IC
Pulse-by-pulse overcurrent limiting (OCL)
Intermittent operation under continuous overcurrent
Low quiescent current drain when shut off by grounding the ON/
OFF
pin
