MAX16992

MAX16990/MAX16992 EVALUATION KIT AVAILABLE 36V, 2.5MHz Automotive Boost/ SEPIC Controllers General Description The MAX16990/MAX16992 are 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 these devices ideal in automotive applications such as for front-end “preboost” or “SEPIC” power supplies and for the first boost stage in highpower LED lighting applications. An internal low-dropout regulator (PVL regulator) with a 5V output voltage enables the MAX16990/MAX16992 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. There are multiple versions of the devices offering one or more of the following functions: a synchronization output (SYNCO) for two-phase operation, an overvoltage protection function using a separate input pin (OVP), and a reference input pin (REFIN) to allow on-the-fly output voltage adjustment. The MAX16990 and MAX16992 operate in different frequency ranges. All versions can be synchronized to an external master clock using the FSET/SYNC input. In addition, the MAX16990/MAX16992 have a factoryprogrammable spread-spectrum option. Both devices are available in compact 12-pin TQFN and 10-pin µMAX® packages.
