Micropower Step-up DC/DC Converter With 150mA Peak Current Limit

The LM2705 is a micropower Step-up DC/DC in a small 5-lead SOT-23 package. 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 and cost in space-conscious portable applications. 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.
