1 / 8 page AIC1580/L Simple PWM Power Regulator with Shutdown Analog Integrations Corporation 4F, 9, Industry E. 9th Rd, Science Based Industrial Park, Hsinchu Taiwan, ROC www.analog.com.tw DS-1580-00 Sep 5, 00 TEL: 886-3-5772500 FAX: 886-3-5772510 1 FEATURES Operation Voltage up to 15V. Simple Voltage-Mode PWM Control. Fast Transient Response. 2V and 1.3V ± 2% Feedback Voltage Reference Option. Adjustable Current Limit without External Sense Resistors. 200KHz Free-Running Oscillator. Short-Circuit Protection with Low Short Circuit Output Current. Low Shutdown Current Built-in Soft Start. APPLICATIONS Power Supply for Motherboard VGTL (1.5V Output) Power Supply for Motherboard VI/O. High-Power 5V to 3.xV DC/DC Regulators. Low-Voltage Distributed Power Supplies. DESCRIPTION The AIC1580 is a high-power, high-efficiency voltage-mode switching regulator controller for motherboard V I/O power supply applications. Designed to drive a N-channel MOSFET in a standard buck topology, the AIC1580 features a high voltage CMOS output driver, short-circuit protection, and 8-pin package. An external 4-bit Digital-to-Analog Converter (DAC) can be used along with the AIC1580 to adjust the output voltage from 2.0V to 3.5V in 0.1V increments. Table 1 on the following page specifies the corresponding output voltage for 16 combinations of DAC inputs as in the typical application circuit. The 200KHz switching frequency allows for using small external components while maintaining high conversion efficiency. The 11MHz bandwidth and 6V/ µS slew rate of the error amplifier ensures high converter bandwidth and fast transient response. The AIC1580 provides adjustable overcurrent and short-circuit protections by sensing the output current across the on resistance of the external N-channel MOSFET rather than an external low value sense resistor. The AIC1580L provides lower reference voltage (1.30V) than the default (2.00V, AIC1580) for lower V OUT requirement. |
