1X/1.5X/2X Charge Pump White LED Driver For Main And Sub-Displays

The APW7001 is a high efficiency Charge Pump white LED driver; the device drives up to four white LEDs in the main Display and up to two white LEDs in the sub-display with regulated constant current for uniform intensity. The supply voltage ranges from 2.7V to 5.5V and it is optimized for a Li-ion battery application. The APW7001 operates in 1x, 1.5x and 2x Charge Pump modes and automatically switches the Charge Pump modes depend on the input voltage to maintain the required power for high power efficiency. The APW7001 provides up to 30mA per LED and allows several methods such as the PWM signals on the ENM pin for main-display dimming and on the ENS pin for sub-display dimming. The two control Logic pins, ENM and ENS, allow disabling or enabling the main and sub-displays. The supply current is only 2mA in 2x mode, and the ENM and ENS are kept low for 20ms will allow the device to enter shutdown mode with 2uA quiescent current. The APW7001 features current limit and short Circuit Protection The APW7001 switches at 1MHz frequency and only requires four 1uF ceramic capacitors and one resistor, and ensures low input current ripple and EMI The APW7001 is available in a 16-pin QFN package.
