ASM8P18xx is a high performance, adjustable frequency, PWM controller with an integrated spread spectrum modulator for EMI reduction. It contains all the functions of a standard PWM controller along with a user configurable spread spectrum modulation with adjustable spread. ASM8P18xx allows significant system cost savings by reducing the number of PCB layers.
30V maximum operating voltage with CMOS technology Adjustable PWM frequencies (40 KHz to 400 KHz) Maximum Output drive current of 1A. Wide duty cycle range (0% minimum to 95% maximum) Spread spectrum modulation with adjustable spread. Under voltage lockout with hysteresis. Low startup current: 275?A maximum Pin compatible with industry standard 3842 PWM controller. Temperature range
–40°C to +85°C. Thermal protection. Frequency skip mode. Available in 8-pin plastic MicroSO, P-DIP and SOIC packages. shutdown, overload and undercurrent
