| 2 Description |
| The MG20U201 is a current feedback control, buck type LED driver IC. It achieves good output current regulation |
| without the need of external compensation components. |
| The MG20U201 integrates a HV start-up circuit, 7~150V linear regulator, precision comparator, PWM control and |
| ring oscillator into one chip. With those building circuits, a precision current output buck mode converter with |
| dimming control (PWM type) can be easily achieved with only few external components. The PWM dimming |
| range is 0~100% duty at a frequency of up to 10KHz. |
| The chip is available in 8-pin SOP package. |
