PRODUCT DESCRIPTION
The EX34063 is a monolithic control circuit containing the primary functions required for
DC-to-DC converters. This device consists of an internal temperature compensated reference,
comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current
output switch.
This device was specifically designed to be incorporated in Step-Down and Step-Up and
Voltage-inverting applications with a minimum number of external components.
