MIC24046

Pin-Programmable, 19V Input, 5A Step-Down Converter

Features

General Description

• 4.5V to 19V Input Voltage Range

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 comput-

ing and telecommunication systems.

• 2.5V to 19V Power Stage Input Voltage Range

with VDDA Externally Applied

• 5A (Maximum) Output Current

• High Efficiency (>90%)

It can be programmed by pin strapping various param-

eters, such as output voltage, switching frequency, and

current-limit values. The pin-selectable switching fre-

quency, valley-current mode control technique,

high-performance error amplifier, and external com-

pensation allow for the best trade-offs 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 Fre-

quency

The MIC24046 is available in a thermally efficient,

space-saving, 20-lead 3 mm × 3 mm VQFN package

with an operating junction temperature range of –40°C

to +125°C.

• Internal Soft-Start and Thermal Shutdown Protec-

tion

• Hiccup-Mode Short-Circuit Protection

• Available in a 20-lead 3 mm × 3 mm VQFN Pack-
