آی سی LN5R12C یک کنترلر PWM با عملکرد بالا، در حالت جریانی است.
he LN5R12C is a high-performance, current-mode PWM Controller. Built-in high-voltage power switch, at 85-265V Of the wide grid voltage range of up to 12W Continued output power. Cost-effective production of bipolar workers Art production of the control chip, combined with high-voltage power tube Integrated package to maximize the savings of the entire product Body cost.
The power controller can operate in a typical Flyback circuit topology, constitute a simple AC / DC power supply converter. IC internal high-voltage start-up current source only VIN resistor with a weak current trigger to complete System startup, to a large extent reduce the VIN resistor power consumption; and in the output power is small IC will To reduce the operating frequency, in order to achieve a very low wait Machine power consumption; patented drive circuit so that the switch is always Work in the critical saturation state, improve the system work For efficiency, so that the system can easily meet the “energy of the Star “on the standby power consumption and efficiency certification requirements.
