Current sense, clock frequencies and amp feedback gain can all be externally regulated. A stable power supply is possible with output currents of up to 1.5A. With output voltage fixed internally, VOUT is selectable in 0.1V increments within a 2.5V ~ 16.0V range (±2.5%). For output voltages outside this range, we recommend the FB version, which has a 0.9V internal reference voltage. Using this version, the required output voltage can be set using 2 external resistors. Switching frequency can also be set externally within a range of 100 ~ 600 kHz and therefore a frequency suited to your particular application can be selected. With the current sense function, peak currents (which flow through the driver transistor and the coil) can be controlled. Soft-start time can be adjusted using external resistor and capacitor. During shutdown (CE pin=L), consumption current can be reduced to as little as 0.5μA (TYP.) or less
