Soft start circuitry is integrated into JTM6291 to avoid inrush current during power on.
After the IC is enabled, the output of error amplifier is clamped by the internal soft-start
function, which causes PWM pulse width increasing slowly and thus reducing input surge
current.
Current Limit Program
A resistor between OC and GND pin programs peak switch current. The resistor value
should be between 10k and 100k. The current limit will be set from 2.5A to 0.5A. Keep
traces at this pin as short as possible. Do not put capacitance at this pin.
