Renesas offers a wide selection of PWM controllers designed for switch-mode DC/DC and AC/DC power supplies requiring an isolation transformer, such as off-line AC/DC and -48V telecom-input DC/DC converters. Included in this broad controllers and converters portfolio are single-ended and double-ended isolated PWM controllers, as well as zero voltage switching (ZVS) full bridge controllers.
