MC33063ADTR

XBLW MC33063 1 .5A Step-Up/Down/Inverting Switching Regulator General Description The MC33063 is a monolithic control circuit containing the primary functions required for DC- to- DC converters. This device consists of an internal temperature compensated reference ( 1.25V ) ,comparator, controlled duty cycle oscillator with an active current limit circuit, driver and high current output switch. The IC is specifically designed to be used in Step- Down and Step- Up and Voltage- Inverting applications with a minimum number of external components. The MC33063 is available in DIP8 and SOP8 package.

In practice, the calculated capacitor value will need to be increased due to its equivalent series resistance and board layout. The ripple voltage should be kept to a low value since it will directly affect the line and load regulation.
