DRAIN VCC ZT SOURCE BR GND FB Datasheet AC/DC Converter IC PWM Type DC/DC Converter IC Integrated Switching MOSFET BM2P064E BM2P104E BM2P134E General Description Key Specifications This series IC is a PWM type DC/DC converter for Power Supply Voltage Operation Range: AC/DC which provides an optimum system for various VCC: 8.90 V to 26.00 V electrical product. It supports both isolated and DRAIN: 650 V(Max) non-isolated devices, enabling simpler design of various types of low power consumption electrical converters. Normal Operating Current: 1.00 mA(Typ) This series also has a built-in starter circuit that can Burst Operating Current: 0.30 mA(Typ) withstand up to 650 V, which contributes to low power Switching Frequency: consumption. Since current mode control is utilized, 1A(BM2P064E): 65 kHz(Typ) current is restricted in each cycle and excellent 1B(BM2P104E): 100 kHz(Typ) performance is demonstrated in bandwidth and 1C(BM2P134E): 130 kHz(Typ) transient response. Switching frequency is fixed at 65 kHz, 100 kHz or 130 kHz. At light load, the switching Operating Temperature Range: -40 C to +105 C frequency is reduced and high efficiency is achieved. A MOSFET ON Resistance: 3.00 (Typ) frequency hopping function is also built-in, which contributes to low EMI. In addition, this product has a built-in super junction MOSFET which has a withstand Package W(Typ) x D(Typ) x H(Max) voltage of 650 V. DIP7AK: 9.27 mm x 6.35 mm x 8.63 mm pitch 2.54 mm Features Switching Frequency=65 kHz, 100 kHz, 130 kHz PWM Current Mode Control Built-in Frequency Hopping Function Burst Operation at Light Load Frequency Reduction Function Built-in 650 V Starter Circuit Built-in 650 V Super Junction MOSFET VCC Pin Under Voltage Protection Applications VCC Pin Over Voltage Protection Household Electrical Appliances, Adapters, etc. Over Current Limiter Function per Cycle Over Current Limiter with AC Voltage Correction Soft Start Function Brown IN/OUT Function ZT Pin OVP Function Typical Application Circuit FUSE OUT Diode Filter Bridge GND Product structure : Silicon integrated circuit This product has no designed protection against radioactive rays .w ww.rohm.com TSZ02201-0F1F0A200350-1-2 2018 ROHM Co., Ltd.
