Clare listed input voltage up to 550V LED driver control IC, can drive 100 series LED group

U.S. Clare listed on the input voltage range of + 8 to 550V LED driver control IC "CPC9909N". Can be controlled from a series of LED groups to more than and 100 series of LED groups of drivers. Of course, you can also control the parallel group drive. For general LED lighting appliances, large screen LCD backlight and digital signage, etc..

New products using the company's own development of BCDMOS (Bipolar/CMOS/DMOS) process technology manufacturing. The pressure for 550V manufacturing technology, SOI (Silicon On Insulator floor). Integrated voltage regulator circuit. The circuit is used to reduce the input voltage to the chip.

The new product uses a peak current to maintain a certain level of PFM (Pulse Frequency Modulation) control mode. Duty cycle can be set to 50%. Built in power MOSFET gate drive circuit. Power MOSFET requires external. Supply current to the LED, with an external resistor set. Use this control IC to get more than 90% conversion efficiency. Dimming function is also available. Two control modes are supported. One is a linear way of controlling the input DC voltage. The other is the input PWM signal to control the PWM mode.

New products using 8 terminal SOP package. 10 thousand bulk purchase price of $0.63. In addition, there are 8 CPC9909NE SOP packages with improved thermal characteristics". 10 thousand bulk purchase price of $0.72.
