Description

Introduction. The LT3439 is a DC transformer driver tailored for applications that require an efficient, low noise isolated step- up or step-down power supply, such. The LT1533 is replaced by an LT3439 which contains no control elements. It simply drives the transformer with 50% duty cycle, controlled switching transitions . 80mA. GND. C2. 820pF.
