DC DC Switching Controllers datasheet and documents for LTC3721EGN-1#PBF
DC DC Switching Controllers Overview
The LTC3721EGN-1#PBF is a push-pull PWM controller from Analog Devices, designed for isolated DC/DC converter applications. It operates within an input voltage range of 10.7 V to 75 V and delivers a regulated output of 9.2 V at up to 1.5 A. The device features a switching frequency of 1 MHz and draws a static current of 3 mA. Packaged in a 16-lead SSOP, it supports operation between -40°C and +85°C.
DC DC Switching Controllers Feature Summary
- Push-pull topology for driving isolated transformer-based converters
- Integrated soft-start and current limit control features
- Wide input voltage capability suitable for industrial power rails
DC DC Switching Controllers Applications
- Isolated DC/DC step-up or step-down converters
- Industrial power supply modules

DC DC Switching Controllers Procurement Notes
Verify the specific suffix GN-1 against the official datasheet to confirm pinout and electrical characteristics match the design requirements. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement decisions.
DC DC Switching Controllers Selection Notes
Select this component when a push-pull topology is required for high-voltage isolated conversion. Ensure the external transformer and MOSFETs support the 1 MHz switching frequency and the 1.5 A output current capability specified in the technical data.
DC DC Switching Controllers Part Context
This part belongs to the LTC3721 family of switch-mode controllers. It is distinct from synchronous buck controllers like the LTC3733 or hot-swap controllers like the LTC4231, serving specifically as a driver for push-pull topologies in isolated power designs.
DC DC Switching Controllers Replacement Considerations
Check for direct substitutes such as the LTC3721EUF-1#PBF which shares the same core functionality but utilizes a 16-QFN package instead of SSOP. Verify pin compatibility and thermal performance differences before substitution.
