Description
PBL38042 is a monolithic integrated circuit designed to power EL (electroluminescent) lamps, motivated to replace the LCD background illumination system in battery-powered handheld devices with a low-power EL-lamp. It is ideally suitable for mobile phones, where current savings are highly significant for both the LCD and keyboard background illumination. The maximum output voltage is 190V, and the minimum voltage is 170V at max.
Specifications and features
- Minimum number of external components for function: 1 choke, 1 filter capacitor and 1 resistor.
- Easy adaption to various lamp specifications.
- Easy dimming function by controlling the duty cycle.
- Extensive current saving feature compared with LEDs.
- Power-down function <<1µA.
- Supply voltage down to 3V.
- Comes in a 3x3 mm package.
- Lights up to 20nF lamp capacitance area depending on lamp parameter nF/cm2.
Application Scenarios
The PBL38042 integrated circuit is particularly well-suited for powering EL lamps in battery-powered handheld devices. It can support various lamp specifications, and its easy-to-use dimming function, which allows the duty cycle to be controlled, is a notable feature. Additionally, the PBL38042 offers significant power savings functionality than LEDs, making it an excellent choice for battery-powered mobile devices.
