It is de- signed for converters in boost topology, and requires few external components. Its power supply is recommended to be provided by an external auxiliary supply which will switch on and off the IC. The IC operates in the CCM with average current control, and in DCM only under light load condition. The switching frequency is trimmed and fixed internally at 65kHz. Both current and voltage loop compensations are done exter- nally to allow full user control. There are various protection features incorporated to en- sure safe system operation conditions. The internal refer- ence is trimmed (5V+2%) to ensure precise protection and output control level. The ICE1PCS02/G is a design variant of ICE1PCS01 to incorporate the new input brown-out protection function and optimised to have a faster startup time with controlled peak startup current. 85 ... 265 VAC EMI-Filter Voltage Loop Compensation Protection Unit Fixed Oscillator Current Loop Compensation PWM Logic Driver ICE1PCS02 /G CCMPFC VCC Auxiliary Supply V OUT Typical Application Ramp Generator ICOMP VSENSE VCOMP ISENSE GND Nonlinear Gain GATE VINS Brown-out |
