High-Voltage CMOS Process with Excellent ESD protection Very Low Startup Current (Typical 5µA) Under Voltage Lockout (UVLO) Current Mode Control with Cycle-by-Cycle Peak .

The special green-mode control is not only to achieve the low power consumption but also to offer a non-audible-noise o.

The LD7550 is a low cost, low startup current, current mode PWM controller with green-mode power-saving operation. The integrated functions such as the leading-edge blanking of the current sensing, internal slope compensation and the small SOT-26 pac.
