MIC2185YQS-TR Description

Short technical summary and product information.

The Micrel Inc. MIC2185YQS-TR is a high-efficiency synchronous boost PWM control IC designed for various power management applications. With an input voltage range spanning from 2.9V to 14V, this IC is suitable for 1- or 2-cell Li-Ion battery-powered devices, as well as fixed 3.3V and 5V systems.

Key electrical specifications include an efficiency of up to 95%, an oscillator frequency of 200kHz/400kHz with sync capability up to 600kHz, and a low shutdown current of 0.5µA. It also features powerful 5Ω output drivers, PWM current mode control, and cycle-by-cycle current limiting. The device includes a programmable undervoltage lockout and a precision 1.245V reference output.

This IC is available in a 16-pin SOIC narrow body package and a 16-pin QSOP package. The operating ambient temperature range is from –40°C to 85°C, making it suitable for noise-sensitive telecommunications applications and other demanding environments.

Applications include 3.3V to 5V conversion in telecom systems, satellite phones, cable modems, and 1- and 2-cell Li-Ion battery operated equipment.
