Overview
The LT8415EDDB#TRPBF is a synchronous step-up DC/DC converter IC manufactured by Analog Devices Inc. It features an integrated N-channel and P-channel MOSFET half-bridge, power switch, Schottky diode, and output disconnect circuitry. The device supports an input voltage range of 2.7V to 36V and provides a single adjustable positive output. It operates with a fixed switching frequency of 1.2MHz and delivers up to 20mA of switch current. The component is housed in a 12-lead WDFN package with an exposed pad.
Feature Summary
- Integrates complementary N-channel and P-channel MOSFET half-bridges for efficient boost conversion
- Includes built-in Schottky diode and output disconnect circuitry for enhanced control
- Supports wide input voltage ranges suitable for battery-powered applications
Applications
- Ultralow power boost converter designs
- Battery-operated portable electronics
- Sensor interface circuits requiring voltage step-up
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the EDDB variant matches the required thermal and electrical specifications for the target application. Cross-reference the manufacturer's latest datasheet to ensure compliance with RoHS standards and material declarations before final procurement decisions.
Selection Notes
Select this component for applications requiring a compact solution with integrated passive components to minimize board space. Consider the 1.2MHz switching frequency for balancing efficiency and component size. Ensure the load current requirements do not exceed the 20mA switch current limit. Evaluate thermal performance given the small WDFN package footprint under maximum operating conditions.
Part Context
This part belongs to the LT8415 family of ultralow power boost converters from Analog Devices. It is designed to replace discrete solutions by integrating multiple power stages into a single monolithic IC. The device complements other PMIC offerings in the company's portfolio focused on energy harvesting and low-power IoT applications.
Replacement Considerations
Direct substitutes include LT8415IDDB#TRMPBF and LT8415EDDB#TRMPBF. Verify pin compatibility and thermal characteristics when swapping between these variants. Ensure the replacement part number matches the required packaging type and temperature grade.
