Product Summary
The LM2704MFX-ADJ is a micropower step-up DC/DC Converter 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 spaceconscious portable applications. The LM2704MFX-ADJ is ideal for LCD panels requiring low current and high efficiency as well as white LED applications for cellular phone back-lighting. The LM2704MFX-ADJ can drive up to 8 white LEDs from a single Li-Ion battery. The applications of the LM2704MFX-ADJ are (1)LCD Bias Supplies; (2)White LED Back-Lighting; (3)Handheld Devices; (4)Digital Cameras; (5)Portable Applications.
