The LTC3335IUDC#TRPBF is suitable for a variety of PMIC, voltage regulator and DC-DC switching regulator applications such as cell phone chargers, USB powered devices, LED drivers, industry standard single-output switching regulators, point-of-load regulators and other general-purpose switchmode power supply designs. It features an adjustable output voltage range of 0.7V - 5.5V, up to 8A output current, input voltage up to 28V, an internal compensation, programmable loop compensation and multiple output filter configurations.

The operating principle of the LTC3335IUDC#TRPBF starts with the regulating loop gaining access to the set point and commanding the output. A linear regulator monitors the output voltage and compares it with the set point to maintain the power level. Feedback voltage created by sensing the regulated output voltage is amplified by an operational amplifier in the device, and the magnitude of the error voltage is compared to the current flowing through the inductor to create a PWM pulse width modulated signal that allows various control outputs to be adjusted. This in turn controls the power switch’s duty cycle and switches the output voltage. The dual mode feature also allows a single LTC3335IUDC#TRPBF to operate in both PWM and forced-continuous operation, enabling lower input and output ripple voltage.

Due to its versatile design and high performance-to-cost ratio, the LTC3335IUDC#TRPBF is ideal for a wide range of applications, making it the perfect choice for design engineers. It is available in the hermetic TO-263 package, so it can safely be used in high temperature, severe environment applications such as automotive and military applications.
