Error Amplifier
Current Sense Comparator
Peak current (IS) determined by the formula: ISMAX=1V/Rs. A small RC filter be required to suppress switch
transients.
OSCI LLAT OR AN D ST AN DBY M ODE
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.
