The TPS60250 is a highly efficient LED driver capable of powering up to five white LEDs for the main display and two additional white LEDs for the sub-display. It allows for precise adjustment of the constant current, ensuring consistent brightness across all LEDs. With its adaptive charge pump mode and low dropout voltage regulator, the TPS60250 achieves excellent efficiency even when operating from a single lithium-ion battery. The device supports I2C communication, offering four programmable enable inputs that make it easy to control individual displays on and off. Additionally, it provides fully independent operation for the secondary display LEDs, which helps reduce power consumption during standby or when the secondary display is not in use. Key features include an input voltage range of 3V to 6V, support for both 1x and 1.5x charge pump configurations, and fully programmable current settings via I2C. It offers 64 dimming levels with a maximum current of 25mA for both main and sub displays, and 4 dimming steps for auxiliary applications with up to 80mA. The sub-LED current matching is accurate up to 2% at light loads, even when each LED operates at just 100µA. The charge pump runs at 750kHz, and the device can deliver a continuous output current of up to 230mA. It also includes various protection and control features such as x-mode switching, built-in soft-start, overcurrent protection, and on/off detection. The TPS60250 is available in a compact 16-pin 3mm × 3mm QFN package, making it ideal for space-constrained designs.
