This application report presents a solution to interfacing the ADS8380 18-bit 600-KSPS serial interface converter to the TMS320C6713 DSP. The hardware solution is made up of existing hardware: the ADS8380EVM 'C6713 DSK and 5-6K Interface Board. The software demonstrates how to use an EDMA and timer peripheral to collect data at 598 kHz. Discussed also are some of the key points to remember when

This application note discusses how to design a multi-phase asynchronous buck regulator using theLM2639 controller.

Power supply applications using current sense transformers require a duty cycle clamp on the pulse width modulator (PWM) to ensure transformer reset. Not all PWMs come with a duty cycle clamp presenting a problem for the power supply designer. This application note shows how to implement a duty cycle clamp by using a simple delay circuit.

The bq20z80 differs from the bq2084 in several areas although all bq2084 features are available in the bq20z80. Both devices support SBS1.1 with SMBus communications but the bq20z80 has many extended SBS commands to enable additional features. The array of bq2084 safety features is expanded in the bq20z80 with a wider range of configuration options. The bq20z80 offers greater flexibility in use
