The LTC7806 is a high performance 2-phase single output synchronous boost converter controller that drives two N-channel power MOSFET stages out-of-phase. Its constant-frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz. High frequency 2-phase operation reduces input and output capacitor requirements and allows the use of smaller inductors compared to the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses, and eases thermal requirements, simplifying high power boost applications. The synchronous PassThru capability also minimizes losses in automotive start-stop applications. The LTC7806 operates from a wide 4.5V to 40V input supply range. When biased from the boost converter output, the LTC7806 can operate from an input supply as low as 1V after start-up. The very low no-load quiescent current extends operating run time in battery powered systems. OPTI-LOOP® compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The LTC7806 features a precision 1.2V reference, a power good output indicator, and an inductor current monitor.
