The LT ®3434 is a 200kHz monolithic buck switching regulator that accepts input voltages up to 60V.
The LT3434 is a high voltage 3A, 200kHz step-down switching regulator designed for applications requiring high efficiency over a wide input voltage range of 3.3V to 60V. It features Burst Mode operation to maintain high efficiency at low currents and utilizes a supply boost capacitor to fully saturate the power switch for fast transient response. The device includes a 1.25V feedback reference voltage, soft-start capability, and a power good flag with a programmable threshold.
