Description
The SC1105 is an asynchronous voltage mode PWM
controller for applications that require an option of two
voltages. An input is provided to select either the input
voltage (VIN) or a user programmed voltage at the
output.
When the PWM is enabled the 200kHz fixed frequency
PWM regulates the output to either a fixed voltage of
1.5V (SC1105) or a user programmed voltage (SC1106).
When the PWM is disabled the high side MOSFET gate is
turned on to deliver the input voltage directly to the
output.
The SC1105/6 internal architecture and functional blocks
are based on the SC1101 integrated circuit, therefore,
the layout guidelines and reference circuits can be readily
applied.
