A built-in start circuit that withstands 650 V helps to keep power consumption low. Both isolated and non-isolated versions are supported, making for simpler design of various types of low-power converters. Switching MOSFET and current detection resistors are external devices, thus achieving a higher degree of freedom in power supply design. The switching frequency is set as fixed. Since current mode control is used, a current limit is imposed in each cycle, and excellent performance is demonstrated in bandwidth and transient response. With a light load, frequency is reduced and higher efficiency is realized. A frequency hopping function is also built in, contributing to low EMI. Also on chip are soft start and burst functions, a per-cycle overcurrent limiter, VCC overvoltage protection, overload protection, and other protection functions. ● Basic Specifications Operating power supply voltage range: VCC 8.9 V to 26.0 V VH: to 600 V Operating current: Normal: 0.60 mA (Typ.) Burst mode: 0.35 mA (Typ.) Oscillation frequency: BM1P105FJ: 100 kHz (Typ.) Operating temperature range: -40°C to +85°C ● Features PWM frequency: 100 kHz PWM current mode method Frequency hopping function Burst operation during light load / Frequency reduction function 650 V start circuit VCC pin undervoltage protection VCC pin overvoltage protection CS pin open protection CS pin Leading-Edge-Blanking function Per-cycle overcurrent limiter function Overcurrent limiter with AC voltage compensation function Soft start function Secondary overcurrent protection circuit ● Package SOP-J8 4.90 mm × 6.00 mm × 1.65 mm pitch 1.27 mm (Typ.)
