ICE2A265 Datasheet

Primary & Secondary Side PWM Controllers


The second generation CoolSET&trade;-F2( ICE2A265 ) provides several special enhancements to satisfy the needs for low power standby and protection features. In standby mode frequency reduction is used to lower the power consumption and support a stable output voltage in this mode. The frequency reduction is limited to 20kHz/21.5 kHz to avoid audible noise. In case of failure modes like open loop, overvoltage or overload due to short circuit the device switches in Auto Restart Mode which is controlled by the internal protection unit. By means of the internal precise peak current limitation, the dimension of the transformer and the secondary diode can be sized lower which leads to more cost effective for the overall system. ICE2A265 Features&bull; 650V/800V avalanche rugged CoolMOS&trade;&bull; Only few external components required&bull; Input Vcc Undervoltage Lockout&bull; 67kHz/100kHz switching frequency&bull; Max duty cycle 72%&bull; Low Power Standby Mode to meet European Commission Requirements&bull; Thermal Shut Down with Auto Restart&bull; Overload and Open Loop Protection&bull; Overvoltage Protection during Auto Restart&bull; Adjustable Peak Current Limitation via external resistor&bull; Overall tolerance of Current Limiting < &plusmn;5%&bull; Internal Leading Edge Blanking&bull; User defined Soft Start&bull; Soft driving for low EMI
