توضیحات محصول

The HT7963 is a high efficiency boost converter with a fixed oscillator frequency for LED backlighting and LED lighting application. The white LED current is setup using an external current setting resistor, which has a low feed-back voltage of only 0.3V. The DIM input allows a wide range of dimming control for LED backlighting or LED lighting. The device offers a full range of protection functions such as power MOSFET over current protection (OCP), IC power supply under voltage lockout (UVLO), over-voltage protection (OVP), output voltage short circuit protection (OSP) and over temperature protection (OTP).
