www.ti.com SNVS558D – MAY 2008 – REVISED APRIL 2013 LM20333 36V, 3A Synchronous Buck Regulator with Frequency Synchronization
Check for Samples: LM20333 FEATURES DESCRIPTION The LM20333 is a full featured synchronous buck
regulator capable of delivering up to 3A of load
current. The current mode control loop is externally
compensated with only two components, offering both
high performance and ease of use. The device is
optimized to work over the input voltage range of
4.5V to 36V making it well suited for high voltage
systems. 1 2 4.5V to 36V Input Voltage Range
