LTC1436ACGN-PLL#TRPBF

DC DC Switching Controllers Overview

The LTC1436ACGN-PLL#TRPBF is a synchronous step-down switching regulator controller from Analog Devices Inc., housed in a 24-lead SSOP package. It operates with an input voltage range of 5.5V to 28V and supports a maximum switching frequency of 400kHz. The device features a duty cycle capability up to 99% and includes integrated soft-start, enable, and power-on reset functions. Designed for high efficiency, it utilizes a synchronous rectifier topology with a single positive output configuration. The component is rated for operation within a temperature range of -40°C to +85°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as per current manufacturer documentation. Ensure the operating temperature grade matches the 'A' designation requirements for your specific environmental conditions. Cross-reference the exact part number with official distributor catalogs to avoid substitution errors.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring precise frequency synchronization or EMI reduction via spread spectrum techniques. The wide input voltage range suits systems powered by 12V or 24V buses. Consider the 24-SSOP package constraints for thermal management and PCB layout space. Evaluate the need for external compensation components based on the target load transient response specifications.

DC DC Switching Controllers Part Context

This part belongs to the LTC1436 family of high-efficiency synchronous buck regulators. The 'A' grade typically denotes extended industrial temperature performance compared to commercial grades. The '#TRPBF' suffix specifies the reel packaging format and lead-free composition. It serves as a core controller for designing compact DC-DC conversion stages in regulated power supplies.

DC DC Switching Controllers Replacement Considerations

Direct substitute: LTC1436AIGN-PLL#PBF (Tube packaging variant). Verify pinout compatibility and ensure the packaging difference does not impact assembly processes. Check if the specific suffix changes any internal electrical characteristics or if they are functionally identical.
