Overview
The LT3460ES5#TRPBF is a high-efficiency step-up DC/DC converter manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 650 kHz, enabling the use of compact external components. The device supports an input voltage range from 2.5 V to 16 V and delivers up to 180 mA of output current. It features a maximum output voltage capability of 36 V and includes a shutdown function for power management. The IC is housed in a TSOT-23-5 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a high-efficiency boost converter topology optimized for space-constrained designs.
- Includes a dedicated shutdown pin to minimize quiescent current during standby modes.
- Utilizes a fixed 650 kHz switching frequency to reduce passive component size.
Applications
- General purpose step-up DC/DC conversion circuits
- Battery-powered portable electronic devices
- Single-cell lithium-ion battery voltage boosting
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the ES5 variant corresponds to the TSOT-23-5 package type required for your PCB layout. Ensure compatibility with the 650 kHz switching frequency regarding electromagnetic interference constraints in your final assembly design.
Selection Notes
Select this component when a compact boost solution is needed for inputs between 2.5 V and 16 V. It is suitable for applications requiring moderate output currents up to 180 mA. Consider the thermal performance in the small TSOT-23-5 package if operating near maximum load conditions or high ambient temperatures.
Part Context
This part belongs to the LT3460 family of general-purpose step-up converters. The family shares core architecture but varies in package options like SC-70-6 or SOT-23-5. The ES5 designation specifically identifies the TSOT-23-5 footprint variant, distinguishing it from other physical form factors within the same electrical specification group.
Replacement Considerations
LT3460ESC6-1#TRPBF offers identical electrical specifications but utilizes an SC-70-6 package instead of TSOT-23-5. Verify footprint compatibility before substitution as the pinout may differ physically despite matching functional parameters.
