Overview
The LT1930ES5#TRPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 1.2 MHz and supports an input voltage range from 2.45 V to 16 V. The device provides a single adjustable output voltage up to 36 V with a maximum switch current of 1 A. It utilizes a TSOT-23-5 package, offers a shutdown feature, and functions within a temperature range of 0°C to 70°C.
Feature Summary
- Integrates a high-efficiency synchronous rectifier architecture for improved power conversion.
- Features a compact ThinSOT package design suitable for space-constrained applications.
- Includes a low-current shutdown mode to minimize standby power consumption.
Applications
- Battery-powered portable equipment requiring efficient voltage boosting
- Industrial control systems utilizing single-supply operation
- Automotive electronics operating within standard voltage ranges
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the ES5 variant meets the required commercial temperature specifications for your application environment. Ensure compatibility with the TSOT-23-5 footprint during PCB layout planning to maintain signal integrity and thermal performance standards.
Selection Notes
Select this component when a 1.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1 A switch current limit against peak load requirements. Evaluate the TSOT-23-5 package constraints regarding thermal dissipation and available board area relative to higher-power regulator options.
Part Context
This part belongs to the LT1930 family of high-power SOT-23 switching regulators. It shares architectural similarities with the LT1930A, which operates at a higher 2.2 MHz frequency. The series is designed to deliver significant power density within minimal surface-mount footprints, serving as a compact solution for various power management needs.
Replacement Considerations
LT1930AES5#TRPBF serves as a compatible alternative within the same product family, offering identical functionality with a higher 2.2 MHz switching frequency.
