The NCP5810 from ON Semiconductor is a new 2 W dual-output DC-DC converter that offers both positive and negative output. The device's output voltage accuracy, high switching frequency, and small package size make it particularly suitable for powering a display driver in active matrix organic light emitting diodes (active matrix OLED or AMOLED) panel, an emerging display technology for portable applications.
Active matrix OLED technology delivers better colour contrast and video playback quality than today's LCD displays, but creates added power management challenges for design engineers. For example, because AMOLED displays are sensitive to changes in power supply voltages, the NCP5810 is designed to provide accurate feedback voltage with 1% tolerance and a fast line transient response with overshoot of 4 mV, given a 500 mV input voltage variation.
Featuring high overall efficiency up to 85% at 1,75 MHz oscillator frequency, this converter delivers what the manufacturer claims is best-in-class performance. In order to complement the slim form factor of AMOLED display, the converter switches at the high 1,75 MHz frequency, allowing the use of small inductors and ceramic capacitors. Its ultra-thin package with 0,55 mm thickness allows the NCP5810 to fit into the thinnest portable design form factor. In addition, it preserves battery power in shut-down mode with a cut-off function that limits the leakage display current to typically 1 mA. Additionally, the NCP5810 features cycle-by-cycle peak current limit and thermal shutdown protection.
