Microchip Technology MIC2186YQS-TR

Description
The MIC2186 is a high-efficiency boost PWM control IC with a wide input voltage range of 2.9V to 14V. It can efficiently boost voltages in 1- or 2-cell Li-ion battery-powered applications, as well as in fixed 3.3V, 5V, or 12V systems. Its powerful 1.60 output driver allows it to supply large output currents with the selection of proper external MOSFETs.
The MIC2186 can be configured to operate at 100kHz, 200kHz, or 400kHz. With its fixed frequency PWM architecture and easily synchronized drive, it is ideal for noise-sensitive telecommunications applications. It also features a low current shutdown mode of 0.5μA and programmable undervoltage lockout. A manually selectable SKIP Mode allows high efficiencies in light load situations.
