1 / 12 page AP1501A 150KHz, 5A PWM BUCK DC/DC CONVERTER AP1501A Rev. 7 1 of 12 SEPTEMBER 2008 www.diodes.com © Diodes Incorporated Lead-free Lead-free Lead-free Lead-free Features General Description The AP1501A series are monolithic ICs that are designed for a step-down DC/DC converter, and possess the ability to drive a 5A load without additional transistor component. Due to reducing the number 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 without external 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 the oscillator frequency. The output version includes fixed 3.3V, 5V, 12V, and an adjustable type. The packages are available in a standard 5-lead TO263 and TO220 packages. • Output voltage: 3.3V, 5V, 12V and adjustable output version • Adjustable version output voltage range, 1.23V to 37V+4% • 150Khz +15% fixed switching frequency • Voltage mode non-synchronous PWM control • Thermal-shutdown and current-limit protection • ON/OFF shutdown control input • Operating voltage can be up to 40V • Output load current: 5A • Low power standby mode • Built-in switching transistor on chip • Lead Free packages: TO263-5L and TO220-5L(R) • TO263-5L: Available in “Green” Molding Compound (No Br, Sb) • Lead Free Finish/RoHS Compliant (Note 1) Applications • Simple High-efficiency step-down regulator • On-card switching regulators • Positive to negative converter Ordering Information Package K5 : TO263-5L Output Version AP1501A - XX XXX X - X Packing U : Tube 13 : Tape & Reel Blank : Adjustable 33 : 3.3V 50 : 5.0V 12 : 12V Lead Free L : Lead Free T5 : TO220-5L T5R : TO220-5L(R) G : Green Tube 13” Tape and Reel Device Package Code Packaging (Note 2) Quantity Part Number Suffix Quantity Part Number Suffix AP1501A-XXK5L-U K5 TO263-5L 50 -U NA NA AP1501A-XXK5L-13 K5 TO263-5L NA NA 800/Tape & Reel -13 AP1501A-XXK5G-U K5 TO263-5L 50 -U NA NA AP1501A-XXK5G-13 K5 TO263-5L NA NA 800/Tape & Reel -13 AP1501A-XXT5L-U T5 TO220-5L 50 -U NA NA AP1501A-XXT5RL-U T5R TO220-5L(R) 50 -U NA NA Notes: 1.
