AnalogicTech introduces a six-channel backlight charge pump

The device supports white LED (light-emitting diode) backlighting and camera flash applications for portable systems (with polymer lithium-ion batteries). The AAT2803 can individually control three independent LED groups (two for backlighting and one for camera flash) and is equipped with seven channels (six for backlighting and one for camera flash). In addition, the AAT2803 greatly saves power and space in handheld devices equipped with two displays, and adds a light load mode to minimize power consumption when the handheld's display is in standby.

KinShum, director of strategic marketing at AnalogicTech, said: "Most of today's handheld devices are equipped with two displays: either a clamshell design (the primary display, the secondary display) or an upright design (with a primary display and backlight). Keyboard). By combining separate control of two separate backlight LED groups (with flash function) with light-load mode, the AAT2803 charge pump can help designers save energy while reducing component count and package size. ”

Maximize efficiency

The backlight charge pump can drive up to six LEDs at 180mA. The device can individually control two sets of four and two LEDs to provide backlighting for the primary and secondary displays. Output operations can be performed independently or in parallel.

The AAT2803 uses AnalogicTech's AS2Cwire(TM) (Advanced Simple Serial Control(TM)) digital interface to turn the LED on, off, or set for any of the 16 log scale ranges.

Four low current settings make it possible to operate in light load mode as low as 50uA (general).

The backlight charge pump operates in 1X, 1.5X, and 2X modes to maximize power efficiency. The operating mode is automatically selected by comparing the forward voltage and input voltage of each LED. The optimized sink current minimizes the voltage space required to drive each LED and maximizes power efficiency by extending the time the device is in 1X mode before switching to 1.5X mode.

Unlike most integrated solutions on the market today, the AAT2803 uses a dedicated charge pump to support backlighting. Therefore, its backlighting operation is not affected by the photographic flash because the photographic flash is driven by a separate charge pump engine.

Flash function

For flash applications, the device enables integration between the charge pump and the regulated output voltage. The circuit's continuous current is up to 120mA and the pulse current is up to 300mA. The circuit also adds a separate start pin to maximize system flexibility.

The AAT2803 has built-in integrated thermal protection that automatically shuts down in the event of an overload short circuit. Its smooth start circuit prevents current overload during start-up. By using a constant switching frequency of 1MHz, designers can support the device with ultra-small ceramic capacitors.

Pricing and listing

The AAT2803 will be available in a lead-free, thermally enhanced 24-pin QFN44 package with a temperature range of minus 40 to 80 degrees. The unit is priced at $1.97 (per 1000 lots).
