Current Sense Comparator

Peak current (IS) determined by the formula: ISMAX=1V/Rs. A small RC filter be required to suppress switch

transients

OSCILLATOR AND STANDBY MODE

We can judge the state of output load through the voltage of Pin 1. In order to reduce the standby power, it will

reduce the OSC frequency at right load. When VCOMP≤2.2V, the OSC frequency begins to reduce. The normal

frequency is 52KHz, the minimum frequency is 22KHz.
