LT1934ES6-1 - High Efficiency Step-Down Converter

The LT1934ES6-1 from Linear Technology is a compact, high-efficiency, step-down DC/DC converter designed for a range of applications requiring a small footprint and high performance. This versatile converter is an excellent choice for portable devices, due to its low quiescent current and the ability to operate from a single Li-Ion cell or multiple alkaline/NiMH cells.

Key Features:

• Wide Input Voltage Range: The device can operate from an input voltage range of 3.6V to 36V, making it suitable for a variety of battery chemistries and configurations.
• Adjustable Output Voltage: The output voltage is adjustable from 1.25V up to 20V, providing flexibility for different circuit requirements.
• High Efficiency: With efficiencies up to 95%, the LT1934ES6-1 maximizes battery life and reduces heat generation.
• Low Quiescent Current: The low quiescent current of only 40µA (typical) during operation makes it ideal for battery-powered applications.
• Internal 1.1A Power Switch: The built-in 1.1A power switch enables the device to deliver significant current for its size.
• Small Package: The device is available in a tiny SOT-23 package, which is ideal for space-constrained applications.
• Thermal Protection: The LT1934ES6-1 includes thermal shutdown to protect the device under high-temperature conditions.
• Stable with Low ESR Ceramic Capacitors: The converter is designed to be stable with ceramic output capacitors, which are smaller, more reliable, and have lower ESR compared to electrolytic capacitors.
