LTC3883EUH-1#TRPBF is a DC/DC switching controller with integrated intelligence and protection, allowing precise control of multiple output voltages. It is mainly used for POL (Point-Of-Load) applications, requiring small packages with high current output. The active switch control provides precise current sharing and dynamic tracking of multiple outputs.

LTC3883EUH-1#TRPBF is an advanced performance DC/DC converter system controller which contains two high-side/low-side MOSFET drivers, a PLL controller and a fully integrated Quadratic Boost controller. The PLL (phase-lock loop) Controller allows the user to set the desired switching frequency (30kHz-1MHz) or to synchronize the switching frequency to an external clock. The Quadratic Boost Controller provides the user the option ofusing linear voltage scaling or current scaling, to provide higher accuracy and better load transient performance.

The LTC3883EUH-1#TRPBF offers a dedicated PMBus communications interface which allows configuration, readings, and control; improving system efficiency and firmware flexibility. The available multiple over current and voltage protection features combined with current sharing, make it suitable for high power, mission critical applications.

The LTC3883EUH-1#TRPBF is an 8-lead SOIC (Shuttle Outline Integrated Circuit) package with an operating temperature range of -40°C to 125°C. The device is mainly used to control multiple outputs of DC/DC converters, providing current sharing and tracking capabilities, as well as wide input range capability and a selectable switching frequency.

Working Principle:

The LTC3883EUH-1#TRPBF uses discontinuous Conduction Mode (DCM) with hysteretic control to regulate the output voltage. The hysteretic frequency is deselected by the user to match the load and input voltage requirements of the system’s power stage. The power level is continuously monitored and the switching frequency adjusted in order to maintain the output voltage within a predetermined range. This will provide an optimal power conversion efficiency and maintain the output voltage within the set limits.

The device also provides current sharing capability across multiple outputs. This will support paralleling and connecting multiple power supplies to ensure an uninterrupted supply of power. The tracking feature will optimize performance across all the power supplies, ensuring accurate current sharing.

The Output Voltage Setup (Vset) is programmed by the user to adjust the output voltage over the full range of 0.6V to 1.5V. This will allow the output voltage to be adjusted to match the load requirements of the system’s power stage. The Vset is adjusted via the PMBus monitor, which will provide additional flexibility and configuration options.

The LTC3883EUH-1#TRPBF will provide system designers with a low current consumption solution, with fast transient response and current sharing features, for POL (Point-Of-Load) applications. The integrated high-side and low-side MOSFET drivers will provide a higher switching frequency, reducing MOSFET temperatures; improving power conversion efficiency and output voltage regulation.
