4.5-V to 42-V Input, 3.5-A Step-Down DC-DC Converter With Soft-Start and Eco-mode™

Check for Samples: TPS54341

FEATURES

DESCRIPTION

The TPS54341 device is a 42-V 3.5-A step-down

regulator with an integrated high-side MOSFET. The

device survives load-dump pulses up to 45 V per ISO

7637. Current mode control provides simple external

compensation and flexible component selection. A

low-ripple pulse-skip mode reduces the no-load

supply current to 152 μA. Shutdown supply current is

reduced to 2 μA when the enable pin is pulled low.

•

High Efficiency at Light Loads with Pulse

•

87-mΩ High-Side MOSFET

152-μA Operating Quiescent Current and

2-μA Shutdown Current

•

100-kHz to 2.5-MHz Adjustable Switching

Frequency

Undervoltage lockout is internally set at 4.3 V but can

increase using an external resistor divider at the

enable pin. The output voltage startup ramp is

controlled by the soft start pin that can also be

configured for sequencing/tracking. An open-drain

power-good signal indicates the output is within 93%

to 106% of the nominal voltage.

•

Synchronizes to External Clock

Low Dropout at Light Loads with Integrated

BOOT Recharge FET

•

Adjustable UVLO Voltage and Hysteresis

UV and OV Power-Good Output

Adjustable Soft-Start and Sequencing

0.8-V 1% Internal Voltage Reference

10-Pin SON with Thermal Pad Package

–40°C to 150°C T_JOperating Range

Supported by WEBENCH^®Software Tool

A wide adjustable switching-frequency range allows

for optimization of either efficiency or external

component size. Cycle-by-cycle current limit,

frequency foldback and thermal shutdown protects

internal and external components during an overload

condition.

APPLICATIONS

The TPS54341 device is available in a 10-pin 4-mm ×

4-mm SON package.
