High Voltage 1 REN Ring Generator

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 pin. The DC-DC Converter frequency of the HV421 is set by PP an external resistor connected between R and V . The SW DD 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 and V . RING DD By Supertex, Inc.
