AP3032KTR Step-Up DC-DC Converter | 1.4MHz Boost Regulator IC | SOT-23-6 Package

AP3032 – High-Efficiency 1MHz Boost Converter for LED Backlighting, SOT-23-6 Package

The AP3032 is a high-performance, inductor-based DC/DC boost converter specifically designed to power up to 4 parallel rows of LEDs, with each row supporting up to 7 LEDs in series—making it ideal for LCD backlighting and portable display applications.

This LED driver IC features a fixed 1MHz PWM control frequency, enabling the use of compact external components such as a 6.8μH inductor and a 1µF aluminum output capacitor, reducing overall PCB footprint and solution cost. The AP3032 delivers efficient, space-saving LED power regulation without compromising performance.

To ensure robust and reliable operation, the AP3032 integrates multiple protection features:

• Output Over-Voltage Protection (OVP) for open-load scenarios

• Under-Voltage Lockout (UVLO)

• Soft-start function to prevent inrush current

• Standby mode for low-power operation

• Current limiting and Over-Temperature Shutdown (OTSD) for overload protection

Compact and easy to implement, the AP3032 is packaged in a space-saving SOT-23-6 form factor, making it well-suited for space-constrained LED backlight solutions in consumer electronics, handheld devices, and battery-powered systems.
