5A Step−Up/Down Inverting Switching Regulator Description: The NTE7173 and NTE 7173SM are monolithic circuits containing the primary functions required for DC−to−DC converters.
These devices consist of an internal temperature compensated reference, comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch.
This series was specifically designed to be incorporated in Step−Down and Step−Up and Voltage−Inverting applications with a minimum number of external components.
Features: D Operation from 3V to 40V Input D Low Standby Current D Output Switch Current 1.
5A D Output Voltage Adjustable D Frequency Operation to 100kHz D Precision 2% Reference Absolute Maximum Ratings: Power Supply Voltage, VCC .
