常見問題解答
What is TPS61170DRVT?
The TPS61170DRVT is a high-efficiency, synchronous boost converter designed by Texas Instruments. It is specifically designed for driving white light emitting diodes (LEDs) in small display and camera flash applications. The device provides a regulated output current with high efficiency and includes features for LED brightness control and protection.
How Does TPS61170DRVT Work?
The TPS61170DRVT works by efficiently converting input voltage to a higher output voltage, suitable for driving LEDs. It utilizes synchronous rectification to minimize switching losses and maximize efficiency. The device also features adjustable LED current and pulse-width modulation (PWM) brightness control to achieve the desired LED brightness levels.
How Many Pins does TPS61170DRVT have and What are the Functions of the Pinout Configuration?
The TPS61170DRVT is housed in a 6-pin SOT-23 package. The pinout configuration includes:
- VIN: Input voltage supply pin.
- SW: Switch node for internal FET connection.
- GND: Ground reference pin.
- FB: Feedback input for LED current regulation.
- EN: Enable pin for turning the device on and off.
- PWM: Pulse-width modulation input for LED brightness control.
What are the Pros and Cons of TPS61170DRVT?
