The Analog Devices Inc. LTC3892MPFE-1-TRPBF is a high-performance, dual-output, synchronous buck (step-down) DC-DC controller. This device features a wide input voltage range of 4.5V to 60V and operates with a selectable switching frequency from 105kHz up to 835kHz, with a typical operating band of 350kHz to 535kHz. Its advanced control features include selectable current limit, enable, frequency control, power good signaling, soft start, and tracking capabilities, facilitating robust power management solutions. The controller is designed for a maximum duty cycle of 99% and offers two output phases, each configured as a positive output driven by transistor drivers.
Housed in a 28-TSSOP-EP package with an exposed pad for enhanced thermal performance, the LTC3892MPFE-1-TRPBF is suitable for demanding applications requiring operation across an extended temperature range of -55°C to 150°C (TJ). Its synchronous rectification topology ensures high efficiency. This component is widely employed in automotive, industrial, and telecommunications power supply designs. The part is supplied on tape and reel.
