PWM Type DC/DC Converter IC

The ROHM PWM type DC/DC converter IC provides an optimum system for various electrical product. It supports both isolated and non-isolated devices, enabling simpler design of various types of low power consumption electrical converters. It also has a built-in starter circuit that can withstand up to 730 V, which contributes to low power consumption. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. At light load, the switching frequency is reduced and high efficiency is achieved.
