詳細說明
Offering exceptional versatility and efficiency, the LT3990IMSE-5#TRPBF is a remarkable adjustable frequency monolithic buck switching regulator that sets a new standard in power management. With an impressive input voltage range of up to 62V and an incredibly low quiescent current consumption of only 2.5μA, this regulator is well-equipped to deliver superior performance in a variety of challenging applications. Its integrated high efficiency switch, catch diode, boost diode, and essential oscillator, control, and logic circuitry ensure a compact and highly functional design. In addition, the LT3990 boasts a low ripple Burst Mode operation, maintaining high efficiency at low output currents while keeping the output ripple below 5mV in typical operating conditions. Thanks to its current mode topology, this regulator provides fast transient response and exceptional loop stability, while the catch diode current limit offers reliable protection against shorted outputs and overvoltage conditions. Furthermore, the LT3990 features an accurate programmable undervoltage lockout function, resulting in an impressively low shutdown current of 0.7μA. With the inclusion of a power good flag to signal when VOUT reaches 90% of the programmed output voltage, this regulator offers unparalleled performance and reliability in a small, thermally enhanced 16-pin MSOP and 3mm × 3mm DFN package
