Pinout
The TPS61160ADRVR is a step-up converter integrated circuit produced by Texas Instruments, primarily used for driving white LEDs. It comes in a 6-pin package, specifically a WSON (DRV) package.
Here are the pin functions:
1. SW (Pin 1): This is the switch pin that connects to the inductor and the Schottky diode. It handles the high-frequency switching of the converter.
2. GND (Pin 2): This is the ground pin and serves as the reference for the IC's internal circuitry.
3. FB (Pin 3): The feedback pin is used to sense the LED current. It connects to the current sense resistor and regulates the LED current by maintaining a constant voltage.
4. CTRL/ENA (Pin 4): This pin serves as the control and enable input. It adjusts the brightness of LEDs through PWM dimming and turns the device on or off.
5. VIN (Pin 5): The input voltage pin supplies the input voltage to the IC. It powers the internal circuitry and drives the LED load.
6. OVP (Pin 6): This is the over-voltage protection pin, which ensures the voltage does not exceed a specified limit to protect the components.
These pins together facilitate the efficient operation of the TPS61160ADRVR in driving LED applications.
