General Description
The Supertex HV421 is a high voltage ring generator designed
to drive 1 North American REN (ringer equivalent number) from
a 5V source. The HV421 has an internal DC-DC converter which
converts the 5V DC supply to a nominal 68V DC connected to the
V
PP
pin. The DC-DC converter frequency of the HV421 is set by
an external resistor connected between R
SW
and V
DD
. The
ringing signal is generated by a high voltage H-bridge which
produces two square waves which are 180 degrees from each
other. The ringing frequency of the H-bridge is set by an external
resistor connected between R
RING
and V
DD
.
