SLASEJ4C April 2017 – February 2023 PGA460
PRODUCTION DATA
The PGA460 device provides efficient burst generation by exciting the primary side of a center-tap transformer connected on the OUTA and OUTB pins through the complementary low-side FETs operating in a current limiting mode. The frequency of the burst is from 30 kHz to 80 kHz with the current limit from 50 mA to 500 mA. The frequency of the burst, the current limit for transformer primary current, and the number of burst pulses can be controlled by using the FREQUENCY, CURR_LIM_P1, CURR_LIM_P12, PULSE_P1, and PULSE_P2 parameters, respectively.
