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.
