Description
The AP2502 is a 4-channel independent linear current sink with low dropout voltage and perfect match between each channel. Each channel can provide 20mA continuous constant current. In application, there is only one 0.1μF ceramic capacitor required, and there is no any EMI and switching noise issue. It is perfect choice for hand-hold portable system especially based on Li-ion/Polymer battery powered display module. The brightness can be control°C and/or adjustable via simple PWM signal applied to EN pin
