DC2202A 42V, 5A Micropower Synchronous Step-Down Silent Switcher Demonstration circuit
The DC2202A is a demonstration circuit designed to evaluate the performance of the LT8640, a micropower synchronous step-down Silent Switcher regulator. The board is configured to provide a 5V output from an input voltage range of 5.7V to 42V, suitable for automotive and industrial applications. It features an integrated EMI filter to ensure compliance with CISPR25 Class 5 limits.
| Input Supply Range | 5.7 to 42 V |
|---|---|
| Output Voltage | 4.85 to 5.15 V |
| Switching Frequency | 1.85 to 2.15 MHz |
| Efficiency | 93.7 % |
The board is designed for a 5.7V to 42V input.
Touch the probe tip directly across the VOUT and GND terminals to avoid long ground leads.
JP1 is grounded at the BURST position by default for low ripple Burst Mode operation.
