Create a design and simulate using EE-Sim tools: MAX16904SAUE33/V+
The MAX16904SAUE33/V+ is a small, synchronous buck converter with integrated high-side and low-side switches. The device is designed to deliver 600mA with input voltages from +3.5V to +28V while using only 25μA quiescent current at no load. Voltage quality can be monitored by observing the PGOOD signal. The MAX16904SAUE33/V+ can operate in dropout by running at 97% duty cycle, making it ideal for automotive and industrial applications. The MAX16904SAUE33/V+ operates at a 2.1MHz frequency, allowing for small external components and reduced output ripple. It guarantees no AM band interference. SYNC input programmability enables three frequency modes for optimized performance: forced fixed-frequency operation, SKIP mode (ultra-low quiescent current of 25μA), and synchronization to an external clock. The MAX16904SAUE33/V+ can be ordered with spread-spectrum frequency modulation, designed to minimize EMI-radiated emissions due to the modulation frequency. The MAX16904SAUE33/V+ is available in a thermally enhanced, 3mm x 3mm, 10-pin TDFN package or a 16-pin TSSOP package. The MAX16904SAUE33/V+ operates over the -40°C to +125°C automotive temperature range.Feature
