Overview
PAM2701 4-Channel Regulated Charge Pump White LED Driver Features n n n n n n n n n n n Description The PAM2701 is a 4-channel charge pump white LED driver, capable of driving up to 4 LEDs in parallel.
The device operates in either 1x mode or 1.
5x fractional mode, and it can switch from 1x mode to 1.
5x mode automatically when the input voltage decreased.
Its internal 4 current sink regulators ensure both the LED current matching and the brightness uniformity.
The LED current can be programmed by an external resistor, R SET, connected between the RSET pin and ground.
LED current of up to 30mA are supported by the input supply voltage over a range of 2.
7V to 5.
5V, making the device optimized ...
