UTC 3563
LINEAR INTEGRATED CIRCUIT
HIGH-EFFICIENCY DC/DC
CONVERTER
DESCRIPTION
The UTC 3563 is a monolithic control circuit
containing the primary functions required for DC to DC
converters and highside-sensed constant current
source. The device consists of an internal temperature
compensated reference, comparator, controlled duty
cycle oscillator with an active current sense circuit,
bootstrapped driver, and high current output switch.
This device is specifically designed to construct a
constant current source for battery chargers with a
minimum number of external components.
Bootstrapped driver can drive the NPN output switch
to saturation for higher efficiency and less heat
dissipation. The UTC 3563 can deliver 1.5A
continuous current without requiring a heat sink.
