DC DC Switching Controllers datasheet and documents for LTC3862IGN-1

LTC3862IGN-1

DC DC Switching Controllers Overview

The LTC3862IGN-1#PBF is a step-up DC/DC controller manufactured by Analog Devices Inc., designed for multi-phase boost and SEPIC topologies. It operates within an input voltage range of 8.5 V to 36 V, supporting a fixed switching frequency of 300 kHz. The device features a single output configuration with a maximum load regulation of -2% and a quiescent supply current of 1.8 mA. It is housed in a 24-pin SSOP package suitable for surface mount installation. The component supports a shutdown function and functions within an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

Supports multi-phase operation for high-current boost and SEPIC applications
Integrates hiccup mode protection for fault management
Enables phase-lockable constant-frequency current mode architecture
Includes dedicated control features such as soft start and clock synchronization

DC DC Switching Controllers Applications

Low emissions diesel fuel injector actuator power supplies
Automotive DC/DC conversion systems requiring robust thermal performance
Industrial power management circuits utilizing boost topology

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., IGN-1 vs EGN-1) against the manufacturer datasheet to confirm the correct industrial temperature rating and package variant. Confirm RoHS compliance status directly from the official specification sheet prior to integration. Ensure the selected part number matches the required pinout and electrical characteristics for the target design.

DC DC Switching Controllers Selection Notes

Select this controller when designing multi-phase boost converters requiring precise current sharing and low electromagnetic interference. Consider the 300 kHz fixed frequency for balancing component size and efficiency. Evaluate the need for hiccup mode protection if the application involves potential short-circuit conditions or thermal stress scenarios during operation.

DC DC Switching Controllers Part Context

This component belongs to the LTC3862-1 series of PolyPhase synchronous boost controllers. It is distinct from other variants like the LTC3862EUH-2#PBF which may offer different pin counts or dual-output capabilities. The IGN-1 designation specifically indicates the industrial temperature grade and SSOP packaging format provided by Analog Devices.
