LINEAR TECHNOLOGY LTC3707EGN#PBF 直流/直流控制器, 高效, 4.5V至28V, 2路输出, 同步降压, 360kHz, SSOP-28
The is a high-performance dual step-down Switching Regulator Controller that drives N-channel synchronous power MOSFET stages. The constant frequency current-mode architecture allows adjustment of the frequency up to 300kHz. Power loss and noise due to the ESR of the input capacitors are minimized by operating the two controller output stages out of phase. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The precision 0.8V reference and power good output indicator are compatible with future microprocessor generations and a wide 3.5 to 30V input supply range encompasses all battery chemistries. A RUN/SS pin for each controller provides both soft-start and optional timed, short-circuit shutdown. Current foldback limits MOSFET dissipation during short-circuit conditions when overcurrent latch-off is disabled.
