Detailed Description

3 A step-down DC-DC converter with a fixed 5.0 V output. PWM control at around 150 kHz for high efficiency. Designed for 12 V and 24 V input systems. Surface-mount power package TO-263-5 for strong thermal performance. Requires simple external components an inductor, a Schottky diode, and input/output capacitors. Suited for power rails in consumer, industrial, and automotive electronics. Main category Integrated Circuits. Small classification Specialized ICs. Available stock 1103 pieces.

Key Features

5.0 V fixed output version of the AP1501 family

Up to 3 A continuous load current with proper thermal design

High efficiency PWM operation around 150 kHz

Wide input range suitable for 12 V and 24 V systems

Internal overcurrent and thermal shutdown protection

Low standby current with shutdown control pin

Stable operation with low ESR capacitors

Minimal external parts for a compact power solution

Surface-mount power package for efficient heat spreading

Key Advantages

Simple, rugged, and cost-effective 5 V buck regulator

Fewer external components reduce BOM and design time

Strong thermal handling in TO-263-5 helps deliver full current

Proven AP-series topology for reliable performance

Well suited for point-of-load conversion from common bus voltages

Packaging

Type Surface-mount TO-263-5 also known as D2PAK-5

Material Molded epoxy body with copper leadframe and tin-plated leads

Size Typical TO-263 footprint compact height and large thermal tab for heat dissipation

Pin configuration 5 leads plus exposed tab common pin functions include VIN switch SW ground GND feedback FB and enable or compensation depending on variant fixed 5 V models use an internal reference for regulation

Thermal characteristics Designed for low thermal resistance to case use a large copper pad under the tab and wide traces on VIN and SW for best cooling and efficiency thermal performance depends strongly on PCB copper area and airflow

Electrical properties Fixed 5.0 V output up to 3 A load PWM around 150 kHz high efficiency with proper inductor and Schottky diode wide input compatibility for 12 V and 24 V systems robust protections against overcurrent and overheating
