Features
Description
• Ease of Use with Few External Components
The ICE1PCS01/G is a 8-pin wide input range controller
• Supports Wide Range
IC for active power factor correction converters. It is de-
• Average Current Control
signed for converters in boost topology, and requires few
• External Current and Voltage Loop Compensation external components. Its power supply is recommended
for Greater User Flexibility
to be provided by an external auxiliary supply which will
• Programmable Operating/Switching Frequency switch on and off the IC.
(50kHz - 250kHz)
The IC operates in the CCM with average current control,
• Max Duty Cycle of 95% (typ) at 125kHz
and in DCM only under light load condition. The switching
• Trimmed Internal Reference Voltage (5V+2%) frequency is programmable by the resistor at pin 4. Both
• VCC Under-Voltage Lockout
compensations for the current and voltage loop are exter-
• Cycle by Cycle Peak Current Limiting
nal to allow full user control.
• Over-Voltage Protection
There are various protection features incorporated to en-
• Open Loop Detection
sure safe system operation conditions. Examples are
• Output Under-Voltage Detection
peak current limitation, brown-out protection and output
• Brown-Out Protection
under voltage detection. The internal reference is trimmed
• Enhanced Dynamic Response
(5V+2%) to ensure precise protection and control level.
• Unique Soft-Start to Limit Start Up Current
The device has an unique soft-start function which limits
• Fulfills Class D Requirements of IEC 1000-3-2 the start up current thus reducing the stress on the boost
diode.
