Overview of UC2825DW

In terms of protection circuitry, the UC2825DW boasts a current limit comparator with a 1V threshold, a TTL compatible shutdown port, and a soft start pin that doubles as a maximum duty cycle clamp. Its fully latched logic ensures jitter-free operation and prevents multiple pulses at the output. Additionally, the under-voltage lockout feature with 800mV of hysteresis guarantees low start-up current, with the outputs transitioning to high impedance during this phase
