The LTC3862CGN is a high-performance, dual-phase step-up (boost) DC/DC controller from Linear Technology, designed to drive N-channel MOSFETs for a high power boost converter. This versatile controller is suitable for applications requiring high voltage outputs with inputs from battery or industrial supplies.

Key Features

• Wide Input Voltage Range: The LTC3862CGN operates over a wide input voltage range, making it ideal for applications with varying input sources.
• Phase-Lockable Fixed Frequency: It features a phase-lockable frequency from 75kHz to 850kHz, allowing for flexibility in balancing efficiency and component size.
• Dual-Phase Operation: The dual-phase operation reduces the required input and output capacitance and allows for the use of smaller inductors compared to single-phase solutions.
• Adjustable Soft-Start: This feature limits inrush current during startup, providing a smoother ramp-up and reducing stress on the power source.
• Current Mode Control: The LTC3862CGN utilizes current mode control for excellent line and load transient response.
• Low Shutdown IQ: The quiescent current in shutdown mode is low, which is beneficial for power conservation in battery-powered systems.
