MIC24046-H

Pin-Programmable, 4.5V − 19V, 5A

Step-Down Converter

General Description

Features

Micrel’s MIC24046-H is

pin-programmable, high-

• 4.5V to 19V input voltage range

• 5A (maximum) output current

• High efficiency (>90%)

efficiency, wide-input range, 5A, synchronous step-down

regulator. The MIC24046-H is perfectly suited for multiple-

voltage rail application environments typically found in

computing and telecommunication systems. It can be

programmed by pin strapping various parameters, such as

output voltage, switching frequency, and current-limit

values. The pin-selectable switching frequency, valley-

current-mode control technique, high-performance error

amplifier, and external compensation allow for the best

tradeoffs between high-efficiency and the smallest

possible solution size.

• Pin-selectable output voltages:

− 0.7V, 0.8V, 0.9V, 1.0V, 1.2V, 1.5V, 1.8V,

2.5V, and 3.3V

• ±1% output voltage accuracy

• Supports safe start-up with pre-biased output

• Pin-selectable current limit and switching frequency

• Internal soft-start and thermal shutdown protection

• Hiccup-mode short-circuit protection

• Available in a 20-pin 3mm × 3mm QFN package

• –40°C to +125°C junction temperature range

The MIC24046-H is pin-out compatible with its I²C-

programmable counterparts from the same family.

The MIC24046-H is available in a thermally-efficient,

space-saving, 20-pin 3mm × 3mm QFN package with an

operating junction temperature range of –40°C to +125°C.

Applications

• Servers, data storage, routers, and base stations

• FPGAs, DSP, and low-voltage ASIC power
