MIC24046
Pin-Programmable, 4.5V -19V, 5A
Step-Down Converter General Description Features The MIC24046 is a pin-programmable, high–efficiency,
wide input range, 5A synchronous step-down regulator.
The MIC24046 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 pinselectable switching frequency, valley-current mode
control technique, high–performance error amplifier, and
external compensation allow for the best trade-offs
between high efficiency and the smallest possible solution
size. The MIC24046 is available in a thermally–efficient, spacesaving, 20–pin 3mm × 3mm QFN package with an
operating junction temperature range of –40°C to +125°C.
