1 .5 A, Sep-Up/Down/Invering Swiching Regulaors GENERAL DESCRIPTION The is a molihic crol circui caining he primary funcis required for DC o DC cverers. These devices csis of an inernal emperaure compensaed reference, comparaor, crolled duy cycle oscillaor wih an acive curren limi circui, driver and high curren oupu swich. This series was specifically designed o be incorporaed in Sep-Down and Sep-Up and Volage Invering applicais wih a minimum number of exernal compens.

This cdii will shoren he ime a frequencies 30 khz,and is magnified a high emperaures. This cdii does no occur wih a Darling cfigurai, since he oupu swich canno saurae.
