Texas Instruments Adjustable Buck DC-DC Converter 500mA WSON-10

Texas Instruments Adjustable Buck DC-DC Converter 500mA is a high-efficiency, synchronous step-down converter rated for up to 500 mA output current from an input range of 4.75 V to 28 V.

Overview

The converter is based on the DCS-Control topology and is suited to systems powered by multi-cell Li-ion batteries, 12 V rails, or higher intermediate supply lines. It automatically enters a power save mode under light load conditions to maintain efficiency across the load range.

Key Features

• Dedicated sleep mode with typical quiescent current of 4.8 µA
• Efficiency at very low load currents can be improved by up to 20% in sleep mode
• Power good output signal for power sequencing and power-on reset functions
• 100% duty cycle mode for lowest dropout operation
• Active output discharge in shutdown mode, with shutdown current less than 2 µA
• Under-voltage lockout, short-circuit protection and over-temperature protection

Package and Handling

The device is supplied in a compact, surface-mount WSON-10 package, suited to space-constrained applications. It is manufactured without antimony or bromine-based flame retardants. The device has limited built-in ESD protection, so during storage and handling the leads should be shorted together or the device placed in conductive foam to prevent electrostatic damage.

Choose this adjustable buck DC-DC converter when you need a compact step-down power solution with a wide input voltage range and dedicated power saving features.
