Description
The TPS60230 features an automatic mode selection between 1.5x and 2x charge pump modes to optimize efficiency. It also offers features like a soft-start function to minimize inrush current during power-up, and thermal and short-circuit protections to enhance reliability. Its small QFN (Quad Flat No-lead) package and minimal external components make it suitable for compact designs. This converter is often used in portable electronics, such as smartphones, tablets, and other handheld devices, where space efficiency and power management are critical.

Features
1. Output Voltage: Provides a regulated output voltage, typically used for driving white LEDs in backlighting applications.
2. Efficiency: Offers high efficiency, typically around 85% at a load of 20 mA, due to its fractional conversion ratios (1, 1.5, and 2).
3. Input Voltage Range: Operates within an input voltage range of 2.7 V to 6 V, making it suitable for battery-powered devices.
4. Current Drive: Capable of driving up to 6 white LEDs with 25 mA each.
5. Low Quiescent Current: Features a low quiescent current of about 0.1 µA in shutdown mode, contributing to extended battery life.
6. Thermal Protection: Includes built-in thermal shutdown protection to prevent overheating.
7. Package: Available in a compact 16-pin QFN package, ideal for space-constrained applications.
8. Soft Start: Incorporates a soft-start feature to limit inrush current during startup.
These features make it suitable for applications like mobile phones, digital cameras, and other portable electronics requiring efficient LED backlighting.
Pinout
- Pin Count: The device is available in a 16-pin VQFN (RGTR) package.
- Function: The TPS60230RGTR is designed to drive up to five white LEDs in series, ensuring uniform brightness. It operates with a fixed switching frequency and provides a regulated output current. The device features soft-start, over-voltage protection, and thermal shutdown for reliable operation. Additionally, it allows for PWM dimming to adjust the brightness of connected LEDs.
