UMW R UMW AP1501 FEATURES GENERAL DESCRIPTION The AP1501 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. The AP1501 series operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Available in a standard 5-lead TO-220 package with several different lead bend options, and a 5-lead TO-263 surface mount package. A standard series of inductors are available from several different manufacturers optimized for use with the AP1501 series. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ±4% tolerance on output voltage under specified input voltage and output load conditions, and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80 µA standby current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault conditions. • • • • • • • • • • • • • • 3.3V, 5V, 12V, and adjustable output versions Adjustable version output voltage range, 1.2V to 37V ±4% max over line and load conditions Available in TO-220 and TO-263 packages Guaranteed 3A output load current Input voltage range up to 40V Requires only 4 external components Excellent line and load regulation specifications 150 kHz fixed frequency internal oscillator TTL shutdown capability Low power standby mode, IQ typically 80 µA High efficiency Uses readily available standard inductors Thermal shutdown and current limit protection APPLICATIONS • • • Simple high-efficiency step-down (buck) regulator On-card switching regulators Positive to negative converter TYPICAL APPLICATION (Fixed Output Voltage Versions) 12V 4 AP 1501 5.0 + 1 2 CIN 5 3 680µF +VIN L1 5.0V +C OUT 220µF BLOCK DIAGRAM ON/ OFF VIN START UP 2.5V + + + COM COM + FEEDBACK R2 GM + AMP Active capacitor LATCH DRIVER + + OUTPUT 150kHz OSC www.umw-ic.com 1 GND 友台半导体有限公司 PDF
