The LTC3787 is a high performance, polyPhase, single output, synchronous boost converter controller for driving two N-channel power MOSFET stages out of phase (metal-oxide-semiconductor-field-effect transistor, The abbreviation of the gold-oxygen half-field effect transistor is a field-effect transistor that can be widely used in analog circuits and digital circuits. The multi-phase operation reduces the input and output capacitor requirements, allowing the use of inductors smaller than similar single-phase solutions. Synchronous rectification improves efficiency, reduces power loss, and reduces thermal requirements for high power boost applications. A 4.5V to 38V input supply range encompasses numerous system architectures and battery chemistries. The LTC3787 can operate from a low-to-2.5V input supply after the converter's output or another auxiliary supply is applied. The device's operating frequency can be set from 50kHz to 900kHz, or The internal PLL is synchronized to an external clock, and multiphase operation enables the LTC3787 to be configured for 2, 3, 4, 6 and 12 phase operation. The SS pin is responsible for enabling the input during startup.
