H1563P / H1563S
HIGH-EFFICIENCY DC/DC CONVERTER
Description
The H1563 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 compensa-
ted reference, comparator, controlled duty cycle oscillator with an active current sense circuit, bootstrap-
ped 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 eff-iciency and less heat dissipation. The H1563
can deliver 1.5A continuous current without requiring a heat sink.

Ripple(P-P)
: Desired peak to peak output ripple voltage in practice, the calculated value will need to be increased due
to the capacitor equivalent series resistance and board layout. The ripple voltage should be kept to a low
value since it will directly effect the line and load regulation.
