LTC3892MPFE-1#PBF

DC DC Switching Controllers Overview

The LTC3892MPFE-1#PBF is a high-performance dual step-down DC/DC switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 60 V and supports output voltages from 800 mV to 59.4 V. The device drives all N-channel synchronous power MOSFET stages, delivering up to 25 A output current across one output channel. Key electrical parameters include a quiescent current of 34 uA and a programmable switching frequency between 105 kHz and 835 kHz. It functions within a temperature range of -55°C to +150°C TJ and utilizes a TSSOP-EP-28 package.

DC DC Switching Controllers Feature Summary

• Drives all N-channel synchronous power MOSFET stages for efficient power conversion
• Minimizes power loss and noise through out-of-phase operation of two controller output stages
• Supports low quiescent current operation for improved efficiency in standby modes

DC DC Switching Controllers Applications

• High efficiency dual-phase step-down 5V/8.5V converter designs
• Dual 5V/12V output synchronous step-down DC/DC controller applications
• Industrial systems requiring wide input voltage ranges up to 60V

DC DC Switching Controllers Procurement Notes

Verify availability status as Mouser indicates limited supply or special order requirements for this part number. Confirm the specific suffix matches the required gate drive voltage variant (e.g., MPFE-1) against design specifications. Ensure compatibility with development kits such as DC1998A or DC2190A series if evaluation is needed prior to production implementation.

DC DC Switching Controllers Selection Notes

Select this component when designing dual-output buck converters requiring independent phase control to reduce ripple. The wide input voltage range suits applications powered by 12V, 24V, or 48V buses. Consider the thermal performance of the TSSOP-EP-28 package for heat dissipation requirements in dense PCB layouts.
