LT1615IS5-1#TRMPBF: Step-Up DC/DC Converter

The LT1615IS5-1#TRMPBF is a high-performance, micropower step-up DC/DC converter from Linear Technology, designed to provide efficient power management for battery-powered and low-voltage systems. This compact and versatile component is ideal for portable devices due to its low quiescent current and high efficiency. The LT1615IS5-1#TRMPBF operates from an input voltage as low as 1.2V, making it suitable for single-cell applications, and can deliver output voltages up to 34V.

Encased in a tiny SOT-23 package, this device is optimized for space-constrained applications, offering a minimal footprint on the PCB. The LT1615IS5-1#TRMPBF features an internal 36V, 350mA switch, which allows it to power loads up to 100mA with ease, depending on input and output voltage conditions. Its internal oscillator runs at a fixed frequency of 1.2MHz, enabling the use of small, low-cost capacitors and inductors while minimizing noise sensitive to RF and other high-frequency circuits.

The LT1615IS5-1#TRMPBF incorporates several protective features such as thermal shutdown, current limiting, and a low-battery detector to safeguard the device and the system it powers. This converter also supports a shutdown mode that reduces quiescent current to less than 1µA, further extending battery life in portable applications.

Key features of the LT1615IS5-1#TRMPBF include:

• Wide input range from 1.2V to 15V
• Adjustable output voltage up to 34V
• High switching frequency of 1.2MHz allows for small external components
