General Description
From initial application of power or from Run mode if VDD falls below VDDSLEEP below VDDREG, the controller changes to Sleep mode.
Non-essential controller circuits are powered down and the external switching transistor (Q1) is held off.
Key Features
- Advanced primary sensing controller achieves true CV/CC output characteristic without opto-coupler.
- Full featured protection for over-temperature, input over-voltage, input under-voltage, output short-circuit.
- Advanced PFM/PWM control and quasi-resonant switching for increased efficiency.
- Switching timing jitter spreads RF spectral emissions, eases EMC compliance.
- SOT23-6 package.
