The LT3502AEDC#TRPBF is a step-down DC/DC converter contained in a 3mm x 3mm DFN package. It features a wide input voltage range of 3.3V to 80V, delivering a continuous output current up to 1A. In addition, it also features a high efficiency, up to 96%, excellent transient response, small size and a proprietary pulse width modulation (PWM) system for improved control and transient behavior. The LT3502AEDC#TRPBF is ideal for applications such as servers, data storage, telecom and networking equipment, medical equipment, and FPGA power systems.

The LT3502AEDC#TRPBF DC/DC converter operates by converting an input voltage that is higher than the output voltage, into an equivalent output voltage. This is achieved by an inductor-capacitor (LC) filter coupled with a pulse width modulation (PWM) system, which switches the voltage and current continuously and precisely. The output voltage is regulated using an internal transconductance error amplifier (TCEA) as feedback and this is adjusted by changing the duty cycle of the PWM input (VIN) pulses.

Working Principle of the LT3502AEDC#TRPBF DC/DC Converter: The LT3502AEDC#TRPBF operates by continuously switching on and off an external power switch at a predetermined frequency and duty cycle. This is done by applying a PWM signal to the power switch at the appropriate frequency and duty cycle, controlling the power switch’s On and Off time. During the On time, energy is stored in the input buffer and during the Off time, the energy is used to produce the output voltage. The voltage output is then measured by an internal error amplifier, which compares it against a voltage reference. If the output voltage is too high or too low, the error amplifier adjusts its feedback to the power switch accordingly, which improves the control of the output voltage.

The LT3502AEDC#TRPBF DC/DC converter has a very wide input voltage range, making it suitable for a variety of different power supply applications. The wide range of input voltage makes it ideal for servers, data storage, telecommunications and networking equipment, medical equipment and FPGA power supplies. This allows the LT3502AEDC#TRPBF to be used in a wide variety of applications and makes it a very versatile DC/DC converter.

The LT3502AEDC#TRPBF is a high efficiency DC/DC converter, up to 96%, due to its high switching frequency and proprietary variable duty cycle PWM system. Additionally it has a low quiescent current (Iq) of just 11μA, making it a good choice for low-power applications. The LT3502AEDC#TRPBF also features an excellent transient response, which allows it to maintain a constant output voltage even in the presence of high input voltage transients. Finally, the LT3502AEDC#TRPBF also features a small 3mm x 3mm package, making it ideal for space-constrained applications.

In conclusion, the LT3502AEDC#TRPBF is a high efficiency, wide input voltage range, high-switch frequency step-down DC/DC converter in a very small 3mm x 3mm package. Its wide range of input voltage and high efficiency make it a great choice for servers, data storage, telecommunications and networking equipment, medical equipment and FPGA power supplies. Furthermore, its excellent transient response, low quiescent current and small package size make it a great choice for a wide variety of applications.
