PDI-A20-24V4AISO – 2-Channel 200 kHz Isolated PWM Driver Interface
PDI-A20-24V4AISO is a two-channel isolated PWM driver interface with programmable frequency and duty-cycle control. It provides 1 Hz – 200 kHz PWM outputs with 0.1 Hz frequency resolution and 0.1% duty-cycle resolution. The isolated and referenceable outputs support 10 V – 24 V output reference levels and provide 4 A peak source and 6 A peak sink current for MOSFET, IGBT, H-bridge, half-bridge, transformer driver, and load control applications.
