Working Principle

The LTC1628IG-SYNC#TRPBF operates as a dual-output, pulse width modulation (PWM) step-down switching controller. The device features a wide input voltage range (4V-16V), programmable target output voltage range (2.70V-5.50V) and fixed reference voltage of 2.25V. This enables a wide range of system power architectures including single-source sources or multiple-source sources such as the combination of wall plug or battery voltage, or multiple battery packs. The device is designed to maximize flexibility and efficiency, and most importantly, improve system wide power delivery. The LTC1628IG-SYNC#TRPBF integrates dual complete high-side and low-side P-channel MOSFETs with an on-board 2:1 soft-start circuit. When enabled, the 2:1 soft-start circuit provides a soft start sequence for both output voltage rails. Additionally, the device supports a wide range of operating frequencies, from fixed frequency modes of 500kHz to 2.25 MHz to adjustable external syncing clock modes. The device also features an internal voltage reference, programmable voltage output range and synchronization options. The internal reference provides a nominal 2.25V reference to the output voltage and provides an additional safety margin for system under voltage and over voltage conditions. Additionally, the output voltage can be programmed via external voltage reference or standard bus commands. Lastly, the device can be synchronized to an external signal from 0.3MHz to 2.25MHz.The LTC1628IG-SYNC#TRPBF operates in a PWM mode with a wide frequency range (500kHz to 2.25MHz). Depending on the selected operating frequency, the devices can switch at up to 10A current. The device also includes thermal shutdown and maximum duty cycle protections, along with over current protection which is set to 1.5x the selected output current. Overall, the LTC1628IG-SYNC#TRPBF is a highly advanced, compact, high-frequency, dual-output, step-down switching controller that is designed for a variety of applications, from simple point-of-load regulation to complex distributed power solutions, and offers maximum flexibility and efficiency, improving system wide power delivery.
