ZSPM1025A / ZSPM1035A Programming and Calibration

2022-05-12

● The ZSPM10X5A (ZSPM1025A/ ZSPM1035A) is delivered without configuration or calibration, so the devices must be programmed prior to the first use. This is typically done using a programming fixture prior to soldering the components on the circuit board or during the end-of-line testing and calibration steps. Note that the devices will not power up their output voltage or react to the OPERATION command until the configuration has been written. This prevents any damage to the application caused by invalid configuration parameters.
● The configuration is stored in a one-time-programmable memory (OTP) integrated in the ZSPM10x5A. Note that the ZSPM10x5A is only programmable once. Two different sets of parameters must be programmed: one for configuration and another for calibration. Configuration parameters are constant over all devices for a given application and can be programmed at any time during production. This includes parameters such as switching frequency and compensation.
