LT1615ES5-1#TRPBF Step-Up DC/DC Converter

The LT1615ES5-1#TRPBF is a highly efficient, compact, and versatile step-up DC/DC converter from Linear Technology, designed to meet the demanding requirements of portable applications. This miniature, high-frequency switching regulator can operate from an input voltage as low as 1.2V, making it ideal for single-cell Li-Ion, or multi-cell alkaline/NiMH applications where the output voltage is higher than the input voltage.

Equipped with a fixed 1.22MHz switching frequency, the LT1615ES5-1#TRPBF minimizes the size of external components, allowing the use of tiny, low-cost capacitors and inductors that are just 2.2µH in size. Despite its small form factor, this device is capable of delivering up to 100mA of continuous output current at a voltage as high as 34V from a 5V input.

The LT1615ES5-1#TRPBF comes in a compact SOT-23 package, which is highly sought after for space-constrained applications. Its low quiescent current of only 20µA (which reduces to 0.5µA in shutdown) makes it an excellent choice for battery-powered devices where extending battery life is crucial.

Featuring a range of built-in protections, the LT1615ES5-1#TRPBF offers both thermal shutdown and current limiting to safeguard the device and your application from potential damage. Its internal soft-start function limits inrush current during startup, further enhancing system reliability.

Key features of the LT1615ES5-1#TRPBF include:

• Wide input voltage range from 1.2V to 15V
• Adjustable output voltage up to 34V
• High switching frequency of 1.22MHz allows for small external components
• Low shutdown current: 0.5µA
• High efficiency: up to 96%
• Internal soft-start function
• Thermal shutdown and current limit protection
• Compact SOT-23 packaging

Whether you are designing power supplies for handheld medical equipment, portable instruments, or any other battery-operated device, the LT1615ES5-1#TRPBF provides a robust, efficient, and space-saving solution.
