Silanna SLE2002-R01 FirePower Evaluation Board
Silanna SLE2002-R01 FirePower Evaluation Board is designed to help evaluate the SL2002, an integrated timing controller, boost voltage regulator, and driver for laser Time-of-Flight (ToF) measurement drive systems. This 400W evaluation board features a resistive load that includes a charge pump circuit, allowing operation from a single cell battery (2.8V to 6V), which is a valuable feature for portable range finder applications. The Silanna SLE2002-R01 FirePower Evaluation Board demonstrates the high peak current and a very narrow laser FWHM pulse, which can be achieved due to the high level of integration of the SL2002 controller.
Features
- Flexible architecture provides laser FWHM pulses of less than 2ns
- High charging efficiency from a single 2.8V to 6V supply
- Integrates needed blocks for charging and firing resonant-mode diode lasers
- Inductor current control offers precise resonant capacitor energy, even with input voltage fluctuations
- <5mW system no load power consumption
- Up to 1MHz rep rate limited by temperature rise in the laser and other board components
