Analog Devices Inc. presents the LTC3787IGN, a PolyPhase® dual-phase synchronous boost controller. This highly efficient DC-DC switching controller features a wide input voltage range of 4.5V to 38V and a maximum duty cycle of 96%, enabling step-up voltage conversion. The device offers precise control over output voltage and current, with integrated features including current limit, enable, frequency control, power good signaling, and soft start.
Designed for robust performance, the LTC3787IGN operates with a switching frequency adjustable from 105kHz to 760kHz and supports dual-phase operation for improved power handling and reduced output ripple. Its architecture includes synchronous rectification for enhanced efficiency. This controller is suitable for demanding applications in the automotive, industrial, and telecommunications sectors. The LTC3787IGN is presented in a 28-SSOP package for surface mount applications and operates across an extended temperature range of -40°C to 125°C (TJ).
