The outputs of the converters are all programmable. Two of the eight LDOs are low noise, well suited for noise critical RF modules. The step-up converters can be used to power peripherals that require voltages higher than the Li-Ion battery, such as class D amplifiers, USB OTG/Host, OLED displays and LED backlight displays. Three high-voltage current sinks are included for LCD backlighting. The programmable current level is adjustable in 150 ?A increments from 0 to 40 mA. In addition, PWM input options offer a simple way of implementing dynamic luminance scaling (DLS).
Each device is housed in a space saving 7x7 mm QFN56 package, operate from a single 2.7 V to 5.5 V supply and are specified over a -40 to +85°C temperature range.
