ANALOG DEVICES MAX17701ATG+
DC/DC Controller, Synchronous Buck, 4.5 V to 60 V Supply, 2.2 MHz, Supercapacitor Charger Controller
產品總覽
MAX17701ATG+ is a synchronous step-down Supercapacitor charger controller. It is a high efficiency, high voltage, Himalaya synchronous, step-down, supercapacitor charger controller designed to operate over an input-voltage range of 4.5V to 60V. After the supercapacitor is charged, the device regulates the no-load output voltage with ±1% accuracy. The output voltage is programmable from 1.25V up to (VDCIN - 2.1V). The supercapacitor charger controller is designed to provide a holistic application solution requiring backup energy storage with a precise charging capability. The device uses an external nMOSFET to provide input supply-side short-circuit protection; thus, preventing supercapacitor discharge. Typical applications are peak power delivery and energy storage, backup power for industrial safety, ride-through last-gasp supplies, portable medical equipment, building and home automation backup power.
- Optimized feature set for Supercapacitor charging, ±4% charging current regulation accuracy
- ±6% charging current monitor accuracy (ISMON), ±1% voltage regulation accuracy
- 125KHz to 2.2MHz adjustable frequency with external clock synchronization (RT/SYNC)
- Reliable operation in adverse environmental conditions, input short-circuit protection (GATEN)
- Safety timer feature (TMR), output overvoltage protection (OVI), cycle-by-cycle overcurrent limit
- Programmable EN/UVLO threshold, status output monitoring using open-drain outputs (FLG1 and FLG2)
- Complies with CISPR32 (EN55032) class B conducted and radiated emissions, overtemperature protection
- Wide -40°C to +125°C ambient operating temperature range
- 24 TQFN-EP package
- Input quiescent current is 2.1mA typical (VIN - VCSN) > 2.1V, VFB = 1.5V)
