MAX16990ATCE/V+ Product Details

The MAX16990ATCE/V+ from Maxim Integrated Products is a 36V, 2.5MHz automotive boost/ SEPIC controller in 12 pin TQFN package. It is a high-performance, current-mode PWM controller with 4µA (typ) shutdown current for wide input voltage range boost/SEPIC converter. The 4.5V to 36V input operating voltage range makes this device ideal in automotive applications such as for front-end "preboost" or "SEPIC" power supplies and for the first boost stage in high power LED lighting applications. An internal low-dropout regulator (PVL regulator) with a 5V output voltage enables the MAX16990ATCE/V+ to operate directly from an automotive battery input. The input operating range can be extended to as low as 2.5V when the converter output is applied to the SUP input. Typical applications include automotive LED lighting, automotive audio/navigation systems and dashboards.


  • Minimized radio interference with 2.5MHz switching frequency above AM radio band
  • Space efficient solution design with minimized external components
  • Spread spectrum simplifies EMI management design
  • Flexibility with available configurations for boost, SEPIC and multiphase applications
  • Adjustable slope compensation, current mode control, internal soft-start (9ms)
  • Protection features support robust automotive applications
  • Operating voltage range down to 4.5V, immune to load-dump transient voltages up to 42V
  • PGOOD output and hiccup mode for enhanced system protection
  • Overtemperature shutdown
  • Automotive AEC-Q100 grade-1 qualified, operating temperature range from -40°C to +125°C
