4 / 8 page High Performance Current Mode PWM Controller AP3842/3/4/5 Anachip Corp. www.anachip.com.tw Rev.1.0 Oct.11, 2004 4/8 Notes:2.These parameters, although guaranteed, are not 100% tested in production. 3.Parameter measured at trip point of latch with VPIN2=0. 4.Gain defined as: ∆VPIN1 A= ∆VPIN3 ; 0≦VPIN3≦0.8V 5.Adjust Vi above the start threshold before setting at 15V. 6.Output frequency equals oscillator frequency for the AP3842 and AP3843. 7.Output frequency is one and half oscillator frequency for the AP3844 and AP3845. Figure 1 : Error Amp Configuration. Zf Zf COMP V FB 2 1 2.5V 0.8 mA Error amp can source or sink up to 0.5mA Figure 2 : Under Voltage Lockout.

Pin 6 should be shunted to ground with a bleeder resistor to prevent activating the power switch with extraneous leakage currents.
