MAX77505 - Analog Devices

MAX77505 4.6A Switching Current Low IQ Buck Converter

The MAX77505 is a low-quiescent current (800nA typ), high-efficiency hysteretic buck converter operating from a 2.5V to 16V input voltage range. The device offers high efficiency over the entire load range. Hence, it is ideal for either a primary battery or four alkaline batterypowered applications, which require long standby/idling time with short working t.
