Controller IC Chip – Max 17020ETJ Max17020 17020 chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0663)

The MAX17020 is a dual Quick-PWM™ step-downpower-supply (SMPS) controller with synchronous rec-tification, intended for main 5V/3.3V or I/O 1.5V/1.05Vpower generation in battery-powered systems. Low-side MOSFET sensing provides a simple low-cost,highly efficient current sense for valley current-limitprotection. Combined with the output overvoltage andundervoltage protection features, this current limitensures robust output supplies.The 5V/3.3V or 1.5V/1.05V SMPS outputs can savepower by operating in pulse-skipping mode or in ultra-sonic mode to avoid audible noise. Ultrasonic modeforces the controller to maintain switching frequenciesgreater than 20kHz at light loads.An internal 100mA linear regulator can be used toeither generate the 5V bias needed for power-up orother lower power “always-on” suspend supplies. Anindependent bypass input allows automatic bypassingof the linear regulator when the SMPS is active.This main controller also includes a secondary feed-back input that triggers an ultrasonic pulse (DL1 turnedon) if the SECFB voltage drops below its threshold volt-age. This refreshes an external charge pump driven byDL1 WITHOUT overcharging the output voltage.The device includes independent shutdown controls tosimplify power-up and power-down sequencing. Toprevent current surges at startup, the internal voltagetarget is slowly ramped up from zero to the final targetover a 1ms period. To prevent the output from ringingbelow ground in shutdown, the internal voltage targetis ramped down from its previous value to zero over a1ms period. Two independent power-good outputssimplify the interface with external controllers.The MAX17020 is a pin-for-pin replacement of theMAX8778
