It Features remote configurability and telemetry monitoring of power management parameters over PMBus- an open standard I2C-based digital interface protocol. The LTP8803-1A is prised of a programmable digital control system with precision mixed-signal circuitry, EEPROM, power MOSFETs, planar transformer, inductors, and supporting ponents. Its high level of integration minimizes ponent count and design time and maximizes flexibility and power density. The LTP8803-1A preserves high efficiency at high conversion ratios by utilizing a resonant switching architecture that eliminates high voltage switching losses. The LTP8803-1A is available in a 22mm × 24mm × 22mm surface-mounted open frame package. All registered trademarks and trademarks are the property of their respective owners.
