Analog Devices Inc. MAX16990/MAX16992 Current-Mode PWM Controllers
Analog Devices MAX16990/MAX16992 Current-Mode PWM Controllers offer a 4.5V to 36V input voltage range, 4µA shutdown current, and -40°C to +125°C temperature range. These devices are available in compact 12-pin TQFN and 10-pin µMAX® packages and are ideal for automotive applications, such as front-end "preboost" or "SEPIC" power supplies due to the 4.5V to 36V input operating range. MAX16990/MAX16992 controllers operate in different frequency ranges, but all versions can be synchronized to an external master clock using the FSET/SYNC input. Analog Devices MAX16990/MAX16992 Current-Mode PWM Controllers are ideal for automotive LED lighting, dashboards, and automotive audio and navigation systems.
