ROHM BM2P016T | Demoboard BM2P016T-EVK-002

Description

The PWM type DC/DC converter (BM2P016T) for AC/DC provides an optimum system for all products that include an electrical outlet. BM2P016T supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. BM2P016T builds in a HV starter circuit that tolerates 650V, and it contributes to low-power consumption. With current detection resistors for switching as external devices, a higher degree of design freedom is achieved. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. The switching frequency is 65 kHz. At light load, the switching frequency is reduced and high efficiency is achieved. A frequency hopping function is also on chip, which contributes to low EMI. We can design easily, because BM2P016T includes the switching MOSFET.
