DESCRIPTION
The LTC®3619B is a dual monolithic synchronous buck regulator using a constant
frequency current mode architecture.
The input supply voltage range is 2.5V to 5.5V, making it ideal for Li-Ion and
USB powered applications. 100% duty cycle capability provides low dropout
operation, extending the run time in battery-operated systems. Low output
voltages are supported with the 0.6V feedback reference voltage. Channel 1 and
channel 2 can supply 400mA and 800mA output current, respectively.
