MAX20058

60V, 1A, Automotive Synchronous

Step-Down DC-DC Converter

General Description

Beneﬁts and Features

● Synchronous DC-DC Converters with Integrated FETs

• 60V Input for 14V and 24V Systems

• Internal Compensation

The MAX20058 is a high-efficiency, high-voltage, syn-

chronous step-down DC-DC converter IC with integrated

MOSFETs that operates over a 4.5V to 60V input. The

converters can deliver up to 1A current. Output voltage is

programmable from 0.8V to 90%V . The feedback volt-

age-regulation accuracy over -40°C to +125°C is ±1.5%.

● Flexibility

• Output Adjustable from 0.8V to 90%V

• 200kHz to 2200kHz Adjustable Frequency with

External Clock Synchronization

The IC features a peak-current-mode-control architecture

and can be operated in the pulse-width modulation (PWM)

or pulse-frequency modulation (PFM) control schemes.

• Programmable Peak Current Limit (1.14A or 1.6A)

●

RESET Output and EN Input (26V max) Simplify

Power Sequencing

The MAX20058 is available in a 12-pin (3mm x 3mm)

side-wettable TDFN package with an exposed pad for

thermal heat dissipation.

● Protection Features and Operating Range Ideal for

Automotive Applications

• Programmable EN/UVLO Threshold

• Adjustable Soft-Start and Prebiased Power-Up

• Thermal Shutdown

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

• AEC-Q100 Qualiﬁed

Applications

● 14V/24V Systems

● Truck Applications
