AP5725WUG-7

AP5725WUG-7 Description

The AP5725WUG-7 from Diodes Incorporated is a high-efficiency DC-DC regulator designed for LED backlighting applications. This surface-mount device integrates an internal switch and operates within a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered and low-voltage systems. With a fixed switching frequency of 1.2MHz, it ensures stable performance while minimizing external component requirements. The device supports PWM dimming for precise brightness control and delivers a maximum output voltage of 26V with a 750mA switch current capability. Packaged in a compact TSOT23-6 form factor and available in Tape & Reel (TR), it is ideal for space-constrained designs.
