The PT6670 is a series of high-output Integrated Switching Regulators (ISRs) designed to provide a
voltage boost function. Housed in a 14-Pin SIP (Single In-line Package), the PT6670 series incorporates regulators for either a +3.3V or +5.0V input and provide output
voltages from +5V to +12V. Applications include power for auxilliary circuits requiring up to 20W.
