FOSHAN, China – Sept 9, 2008 –ON Semiconductor (Nasdaq: ONNN), a global leader in efficient power solutions, today announced that Chigo Group’s Foshan Zhonggewei Electronics has selected its NCP1027 to power new Chigo air-conditioner line to achieve higher active-mode efficiency and lower standby power consumption.
ON Semiconductor's NCP1027 offers a new solution for Chigo air-conditioners at 10 watts (W) output power level. The company’s proprietary skip-cycle operation enables air-conditions to run at low peak currents. Its high-voltage technology features a built-in 700 V MOSFET with a startup current source, all directly connected to the bulk capacitor. To prevent lethal runaway in low input voltage conditions, an adjustable brown-out circuitry blocks the activity until sufficient input level is reached. Current-mode operation together with adjustable ramp compensation offers superior performance.
Protection wise, a timer detects an overload or a short-circuit and stops all operations, ensuring a safe auto-recovery, low duty cycle burst operation of Chigo air-conditioners. An integrated, auto-recovery, overvoltage protection permanently monitors the VCC level and temporarily shuts down the driving pulses in case of an unexpected feedback loop runaway. Finally, a great RDS(on) figure makes the circuit an excellent choice for standby power supplies to less than 1 W.
"We are excited that our air-conditioners can achieve even higher active-mode efficiency and lower standby power consumption with ON Semiconductor’s solution," said Xu Lin, chief engineer of Chigo Group’s Foshan Zhonggewei Electronics. “The NCP1027 fully meets our requirements for energy-efficient air-conditioners because it offers higher efficiency, lower standby power, reliability and stability, wider input voltage range and better protection performance in smaller size and lighter weight."
"This air-conditioning order reflects Chigo Group’s confidence in ON Semiconductor in achieving our goal—to be the power efficiency benchmark for the semiconductor industry," said Darrell Lim, ON Semiconductor regional vice president of Sales for China. "The design collaboration signifies how the two companies effectively leverage each other’s strengths to provide highly efficient products for the China market."
