DC1488A-C: Demo Board for the LTC2634-12 Quad 12-Rail-to-Rail DACs with 10ppm/°C Reference.

The LTC2941 measures battery charge state in battery-supplied handheld PC and portable product applications. Its operating range is perfectly suited for single-cell Li-Ion batteries. A precision coulomb counter integrates current through a sense resistor between the battery?s positive terminal and the load or charger. The measured charge is stored in internal registers. An SMBus/I2C interface accesses and configures the device.The LTC2941 features programmable high and low thresholds for accumulated charge. If a threshold is exceeded, the device communicates an alert using either the SMBus alert protocol or by setting a flag in the internal status register.The LTC2941 requires only a single low value external sense resistor to set the current range.

Demonstration circuit 1510A is a high output voltage, high efficiency synchronous poly-phase buck converter featuring the LTC3858EUH. The demo circuit is available in two versions. The input voltage of both versions is 16V to 26V. DC1510A-A is configured using 2 LTC3858's with 4 phase interleaving operation which provides a 12V/50A output, while the DC1510A-B is configured with 1 LTC3858 with 2 phase inter-leaving operation which provides a 12V/25A output.

Demonstration circuit 1516A is a 1.5V/15A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 24V. The demo board comes in two versions. The -A version uses inductor DCR current sensing with an iron powder inductor for highest efficiency. The -B version uses a 2.5mΩ/1% sense resistor for accurate current sensing with a low DCR ferrite inductor. The fixed on-time valley current mode control of the LTC3833 allows for a fast load step response.
