Аппаратные драйверы ЖКД LM2705MF-ADJ

Импульсный повышающий DC-DC стабилизатор , регулируемый, 2.2В-7В (Vin), 20В/150мА выход, SOT-23-5

The LM2705MF-ADJ is a micropower step-up DC-to-DC Converter for use with LCD bias supplies. A current limited, fixed OFF-time control scheme conserves operating current resulting in high efficiency over a wide range of load conditions. The 21V switch allows for output voltages as high as 20V. The low 400ns OFF-time permits the use of tiny, low profile inductors and capacitors to minimize footprint. The LM2705 is ideal for LCD panels requiring low current and high efficiency as well as white LED applications for cellular phone back-lighting. The LM2705 can drive up to 3 white LEDs from a single Li-ion battery. The low peak inductor current of the LM2705 makes it ideal for USB applications.
