MAX16990AUBA/V+

The MAX16990AUBA/V+ is a 36V automotive boost/ SEPIC controller in 10 pin µMAX package. It is a high-performance, current-mode PWM controllers with 4µA (typ) shutdown current for wide input voltage range boost/SEPIC converters. 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 MAX16990 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.

• Switching frequency range from 220KHz to 1MHz
• Space efficient solution design with minimized external components
• 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
