Introduction to the MAX17532:
The MAX17532 high-efficiency, high-voltage, synchronous step-down DC-DC converter with built-in MOSFETs operates from a 4V to 42V input voltage range. The converter delivers up to 100mA of output current with an output voltage of 0.8V to 0.9 x VIN. The feedback (FB) voltage accuracy is within ±1.75% over the -40°C to +125°C operating temperature range.
Key features of the MAX17532:
Reduce external components and reduce overall cost without Schottky synchronous internal compensation, stable operation at any output voltage. Built-in soft-start all-ceramic capacitor design provides compact layout
Reduce DC-DC regulator inventory
4V to 42V wide input range
Adjustable output from 0.8V to 0.9 x VIN
100kHz to 2.2MHz adjustable switching frequency range, out-of-band synchronization
Reduce power consumption
22μA quiescent current peak efficiency is higher than 90%
PFM support enhances light load efficiency
1.2μA shutdown current
Working in harsh environments, reliable peak current limit protection, built-in output voltage monitoring, active low RESET
Programmable EN/UVLO threshold monotonic startup into pre-biased load state overtemperature protection
-40°C to +125°C operating temperature range
