High want Electronics Supply LED | LED lamp driver IC [supply] | LED electronic supply is provided by a high want. Shenzhen High-think Electronic Technology Co. located in Bao'an District Longhua Industrial Equipment Hang District, Shenzhen City, Guangdong Shenzhen, Contact: Miss Hu AP3101 as programmable control in normal operation, and for setting osillating externalresistor frequency. Whenoutput smp below a given level, IC automatically enters skip cycle mode to reduce power consumption. 30μa low start-up current and low oper-ating current horse 3, started AP3101 can reduce standbypower dissipation resistance, and improveoperating efficiency. In addition, the driver outputstage 0.6 drivingMOSFET totem direct traffic is helpful. Built-in power control is limited, Ms. AP3101can 23 turn off the PWM output in overload conditions orshort circuit, input power aSMPS can drop close to zero, a perfect protec-tion against overheating automatic per-formed. In addition, leading edge blanking techniques include noise immu-nity AP3101; built-in slope compensation ensures stabilityof peak current mode control. Figure 1 is a block diagram of AP3101.Figure 2 pin configuration is AP3101 AP3008 is 1.2 mhz PWM increase switching white LED driverapplications regu-lator for the current design. AP3008 can drive a string 2--3 white LEDsfrom 2
