On November 6, 2014, Micrel Korea (CEO Young Jun Oh, www.micrel.com), an industry leader in high-performance linear and power solutions as well as LAN, timing and communication solutions, announced that it is supplying the MIC45205, MIC45208, and MIC45212 DC-DC power module product families, which offer peak efficiency of over 93%. These product families are synchronous step-down regulator modules equipped with Micrel's proprietary adaptive ON-time control architecture.

This module product family integrates a DC-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor, and inductor all in a single package, enabling developers to simplify the design and layout process. Through this highly integrated solution, system design can be implemented more easily, and the product time-to-market can be shortened. The internal MOSFETs and inductors are optimized to achieve high efficiency at low output voltages. With a fully optimized design, the devices can deliver up to 6A, 10A, and 14A of current in an input voltage range of 4.5V to 26V, and no additional cooling equipment is required.

The MIC45205, MIC45208, MIC45212-1 utilize Micrel's Hyperlight Load™ architecture, while the MIC45205, MIC45208, MIC45212-2 adopt the Hyperspeed Control™ architecture, enabling ultra-fast load transient response and reduced output capacitance. These module product families feature 1% output accuracy and are adjustable from 0.8V to 5.5V using two external resistors.

In addition, they include over-temperature shutdown protection and input undervoltage lockout, adjustable current limiting, and short-circuit protection functions, with pre-biased output enabling safe startup. The MIC45205, MIC45208, and MIC45212 power module product families are suitable for high power density POL (Point-of-Load) conversion and applications including servers, routers, networking, base stations, FPGAs, DSPs, low-voltage ASIC power supplies, industrial and medical equipment. They feature a junction temperature range of -40°C to +125°C and are supplied in QFN packages.
