IP35063J SEME-LAB [Seme LAB], IP35063J Datasheet - Page 2

• Manufacturer Part Number: IP35063J
• Description: DC-DC CONVERTER CONTROL CIRCUIT
• Manufacturer: SEME-LAB [Seme LAB]

DESCRIPTION
functions required to implement DC–DC converters.
Included are internal voltage reference, comparator,
controlled duty cycle oscillator with current limit circuit,
driver, and high current output switch. This series was
specifically designed to be incorporated in Step-Down
(Buck) and Step-Up (Boost) applications with a minimum
number of external components.
