MAX16990ATCE/V+

The MAX16990ATCE/V+ 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 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.
