SE34063 is a monolithic switching regulator
control circuit containing the primary functions
required for DC-DC converters. This device
consists of internal temperature compensated
reference, voltage comparator, controlled duty
cycle oscillator with active current limit circuit,
driver and high current output switch. The device
is specifically designed to be used in Step-Down,
Step-Up and Voltage-Inverting applications with a
minimum number of external components.
SE34063 is the enhanced version with the
ability to work in higher frequency.
SE34063 is available in 2 packages: SOP- 8
and DIP-8.
