Integrating 1.2 A boost converter and LED driver circuit into 1.3 x 1.3 mm chip scale package, Models MIC2873/MIC2874 operate from 2.7–5.5 V and feature up to 92% efficiency. High switching frequencies of 2 MHz for MIC2873 and 4 MHz for MIC2874 allow use of miniature size chip inductor and small input/output capacitors. Operating in either flash or torch mode, devices can provide boost or linear output using single wire communication interface or through external pins.
