The AA18343 is a monolithic switching regulator control circuit containing the primary
functions required for DC-DC converters. This device consists of internal temperature
compensated reference, voltage comparator, controlled duty cycle oscillator with active
current limit circuit, driver and high current output switch. This device is specifically
designed to be used in Step-Down, Step-Up and Voltage-Inverting applications with
a minimum number of external components.
The AA18343 is available in 2 packages: SOIC-8 and DIP-8.
