General Description
The LM22677 series of
regulators are monolithic integrated circuits which provide all of the active functions for a stepdown (buck) switching
regulator capable of driving up to 5A loads with excellent line and load regulation characteristics.
High efficiency (90%) is obtained through the use of a low ON-resistance N-channel MOSFET.
The series consists of a fixed 5V output and an adjustable version.
