www.DataSheet4U.com AE1501 PWM BUCK DC/DC CONVERTER AE1501 ● Features 3.3V, 5V, two fixed output versions TO-263 package Output load current 3A Input voltage range up to 40V Requires only 4 external components 150 kHz fixed frequency internal oscillator TTL shutdown capability Low power standby mode, IQ typically 85 µA High efficiency Thermal shutdown and current limit protection ● General Description The AE1501 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 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 AE1501 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 5-lead TO-263 surface mount package. Other features include a guaranteed ±5% tolerance on output voltage under specified input voltage and output load conditions, and±15% on the oscillator frequency. External shutdown is included, featuring typically 85µA standby current. Selfprotection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault c...
