SHUTDOWN INPUT (SD)
Shutdown mode. If left unconnected or tied to the VIN pin, the
device will be in Normal mode. The pin has an internal pull-
up of 1.5 MΩ.
REFERENCE VOLTAGE INPUT (VREFIN)
this pin.
Analog Integrated Circuit Device Data
Freescale Semiconductor
If this pin is tied to the GND pin, the device will be in
The output of channel two will track the voltage applied at
FREQUENCY ADJUSTMENT INPUT (FREQ)
by connecting this pin to an external resistor divider between
VDDI and GND pins. The default switching frequency (FREQ
pin connected to ground, GND) is set at 1.0 MHz.
SOFT START ADJUSTMENT INPUT (ILIM1, ILIM2)
1.25 V and VDDI on each ILIM pin.
The buck converters switching frequency can be adjusted
Soft Start can be adjusted by applying a voltage between
