What are the key specifications of the STI9287C?

It features a 2.5V to 5.5V input range, 30V OVP, 1.2MHz switching frequency, 200mV feedback voltage, and an integrated 150mΩ power MOSFET.

How is LED brightness controlled?

Brightness is controlled via the EN/PWM pin using a PWM signal, where the average LED current is proportional to the PWM duty cycle.

What should engineers review before using the STI9287C?

Engineers should verify the output voltage requirements, ensure the inductor and capacitor values are selected according to the application's load, and strictly follow the layout guidelines.

What is the pinout of STI9287C?

Use the STI9287C datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about STI9287C pinout to locate pins, power rails, and interface signals before layout.
