BM1Pxxx supports both isolated and non-isolated devices, enabling simpler design of various types of low-power electrical converters. BM1Pxxx built in a HV starter circuit that tolerates 650V, it contributes to low-power consumption. With switching MOSFET and current detection resistors as external devices, a higher degree of design freedom is achieved. Switching frequency adopts fixed system. 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. A frequency hopping function is also on chip, which contributes to low EMI. BM1Pxxx also has built-in function such as soft start, burst mode, over current limiter per cycle, VCC over voltage protection and over load protection. ●Basic specifications Operating Power Supply Voltage Range: VCC 8.9V to 26.0V VH: to 600V Operating Current: Normal Mode:0.60mA (Typ) Burst Mode: 0.35mA (Typ) Oscillation Frequency: BM1P06xFJ:65kHz (Typ) BM1P10xFJ:100kHz (Typ) Operating Temperature: - 40deg. to +105deg. ●Features PWM frequency : 65kHz, 100kHz PWM current mode method Frequency Hopping function Burst operation / Frequency reduction function when load is light Built-in 650V start circuit VCC pin under voltage protection VCC pin over voltage protection CS pin Open protection CS pin Leading-Edge-Blanking function Per-cycle over current protection circuit Current protection with AC voltage compensation Soft start Secondary Over current protection circuit ●Package SOP-J8 4.90mm×3.90mm ×1.65mm Pitch 1.27mm (Typ) (Typ) (Typ) (Typ) ●Applications AC adapters and household appliances (vacuum cleaners, humidifiers, air cleaners, air conditioners, IH cooking heaters, rice cookers, etc. ●Application circuit ●Line-Up Figure 1.Application circuit Frequency VCCOVP BM1P101FJ 100kHz Auto Restart BM1P102FJ 100kHz Latch BM1P061FJ 65kHz Auto Restart BM1P062FJ 65kHz Latch |
