DIODES Incorporated LED Drivers AP3607FNTR-G1

The AP3607FNTR-G1 is a step-up DC-DC converter designed for driving up to 6 white LEDs (WLEDs) with a maximum output current of 20mA per LED. It operates within a supply voltage range of 2.7V to 5.5V, making it suitable for applications powered by Li-ion batteries. The device features 16 steps of brightness control through a digital pulse dimming function, allowing for precise adjustment of LED brightness. With a high switching frequency of 1MHz, it enables the use of smaller external capacitors, which can help reduce the overall size of the circuit. The AP3607 includes built-in protections such as output over-voltage protection, under-voltage lockout (UVLO), and over-temperature shutdown (OTSD). It is packaged in a compact QFN-3vó3-16 format, suitable for space-constrained applications like mobile phones and portable devices. The operating temperature range is from -40¬8C to 85¬8C, ensuring reliability in various environmental conditions.
