MAX25262AFOB/VY+

MAX25262AFOB/VY+ is a small, automotive synchronous mini buck converter with integrated high-side and low-side switch. The device is designed to deliver up to 2A with 3.5V to 65V input voltages while using only 3.5μA quiescent current at no load. The IC comes with a small 20ns minimum on-time capability, which enables large step-down conversions in a single stage without skipping cycles. A max duty cycle of 98% and low high side FET ON resistance enable a low dropout operation for low input voltage applications. The voltage quality can be monitored by observing the PGOOD signal. The device offers two fixed 5V and 3.3V output voltages. In addition, the device can be configured for 1V to 20V output voltages using an external resistor divider. Applications include double battery automotive systems, automotive instrument clusters, distributed DC power systems, navigation, and radio head units.
