MAX20073/MAX20074

Single 2A/3A 2.2MHz Low-Voltage

Step-Down DC-DC Converters

General Description

Beneﬁts and Features

● High-Feature Set in Ultra-Small Footprint

The MAX20073/MAX20074 high-efficiency switching

regulator family delivers up to 3A load current from 0.5V to

3.8V. The devices operate from an input voltage range of

2.7V to 5.5V, making them ideal for on-board point-of-load

and post-regulation applications. Total output error is less

than ±1.5% over load, line, and temperature.

• High-Eﬃciency DC-DC Converter

• Up to 3A Output Current

• 2.7V to 5.5V Operating Supply Voltage

• Resistor-Adjustable or Factory-Preset

Output Voltage

• Synchronizable, 2.2MHz Switching-Frequency

Enable Input

• RESET Output

The devices feature fixed-frequency PWM mode of opera-

tion, with a 2.2MHz switching frequency. High-frequency

operation enables an all-ceramic capacitor design and

small external components.

• Spread-Spectrum Enable Input

• Forced-PWM and Skip Modes

• Current-Mode Architecture

• 3mm x 3mm x 0.85mm 10-Pin TDFN

● High Precision

The low-resistance on-chip switches ensure high efficiency

at heavy loads while minimizing critical inductances,

making the layout a much simpler task with respect to

discrete solutions. Following a simple layout and footprint

ensures first-pass success in new designs.

• 107% Overvoltage Monitor

• 93% Undervoltage Monitor

• ±1.5% Output-Voltage Accuracy

• Excellent Load Transient Performance

• Overtemperature and Short-Circuit Protection

• -40°C to +125°C Operating Temperature Range

The devices provide an enable input, spread-spectrum

enable input, and RESET output. The output voltage can

be preset at the factory to allow customers to achieve

±1.5% output-voltage accuracy without using expensive

0.1% external resistors. In addition, the output voltage

can be set to any customer value by using two external

resistors at the feedback with 0.5V internal reference. The

device offers a fixed 0.85ms soft-start time.

The 10-pin TDFN exposed pad devices include

overtemperature shutdown and overcurrent limiting. All

devices are designed to operate over the -40°C to +125°C

ambient temperature range.
