This is terribly straightforward electronic circuit project of twin reduction power-supply (smps) controller circuit victimisation the MAX17031. twin reduction power-supply (SMPS) controller are often designed a really straightforward high potency power provide circuit with synchronous rectification, supposed for main 5V/3.3V power generation in powered systems.
Low-side MOSFET sensing provides a simple low-cost, highly efficient current sense for valley current-limit protection. Combined with the output overvoltage and undervoltage protection features, this current limit ensures robust output supplies.
The device includes independent shutdown controls with well-defined logic thresholds to simplify power-up and power-down sequencing. To prevent current surges at startup, the internal voltage target is slowly ramped up from zero to the final target over a 1ms period.
The Max17031 can be used in applications like : Notebook Computers , Ultra-Mobile PC , Main System Supply (5V and 3.3V Supplies), 2 to 4 Li+ Cells Battery-Powered Devices , Telecommunication
Main features of Max 17031 are : Dual Quick-PWM , Preset 5V and 3.3V Outputs , Internal 100mA, 5V Linear Regulator , Internal OUT1 LDO5 Bypass Switch , Secondary Feedback (SKIP Input) Maintains Charge Pump , 3.3V, 5mA Real-Time Clock (RTC) Power (Always On) , 2V ±1% 50μA Reference , 6V to 24V Input Range , Pulse-Skipping/Forced-PWM/Ultrasonic Mode Control , Independent SMPS and LDO5 Enable Controls , Combined SMPS PGOOD Outputs , Minimal Component Count.
