The 2PCS06, ICE2PCS06, ICE2PCS06G is a 8-pin wide input range controller IC for active power factor correction converters. It is designed 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 externally to allow full user control.

Description :

Obsolete as of 25-Nov-2012

The highly integrated IC PWM controller provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions.

Under zero-load and very light-load conditions, The Device saves PWM pulses by entering deep burst mode. This burst mode function enables the power supply to meet international power conservation requirements.

6754MR integrates a frequency-hopping function internally to reduce EMI emission of a power supply with minimum line filters.Built-in synchronized slope compensation is accomplished by proprietary HV monitor to adjust VLimit for constant output power limit over universal AC input range. Also, the gate output is clamped at 13V to protect the external MOSFET from over-voltage damage.

Other protection functions include AC input brownout protection with hysteresis and V_DD over-voltage protection. For over-temperature protection, an external NTC thermistor can be applied to sense the external switcher’s temperature. When V_DD OVP or OTP are activated, an internal latch circuit is used to latch-off the controller. The latch mode is reset when the V_DD supply is removed.
