LD7552 controller equivalent, green mode pwm controller.
z
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 Pe.
The special green-mode control does not only achieve low power consumption but also offer a non-audible-noise operation.
The LD7552 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 package pr.
