AP1501A-50K5G-13 Switching Voltage Regulators BUCK CONV PWM 150KHz 5A 4.5-40V 1.23V DC-DC Voltage Converter

1.Description

The AP1501A series are monolithic ICs that are designedfor astep-down DC/DC converter, and possess the abilityto drive a 5A load without additional transistor component. Due to reducing thenumber of external component, the board space can be saved easily. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control have good line and load regulation withoutexternal design. Regarding protected function, thermal shutdown is to prevent over temperature operating from damage, and current limit is against over current operating of the output switch. The AP1501A series operates at a switching frequency of 150kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Other features include a guaranteed ±4%tolerance on output voltage under specified input voltage and output load conditions, and ±15% on theoscillator frequency. The output version includes fixed 3.3V, 5V, 12Vand an adjustable type. The packages are available in a standard 5-lead TO263-5,TO220-5 and TO220-5 (R)packages.
