YKW-06 － Step-down Switching Controller

GENERAL DESCRIPTION

The YKW-06 is a step-down DC-DC converter. It could drivers an external power transistor using the

PWM control.

The IC incorporates the soft-start function with a proper capacitor connected between SS and

ground pins. The soft-start function could ensure the PWM output pulse width starts from 0% duty cycle.

The output voltage is controlled by the external sense resistor and FB pin. The output voltage are also

adjustable by the external variable resistor connected through SS and BRT pins. Through changing this

external resistor value, could tune the output current and voltage. It also has the over voltage detection

function with debounce-timer check to prevent from the over voltage damage.
