MAX256ASA+ - Maxim Integrated Function Overview

The MAX256ASA+ is an integrated primary-side transformer H-bridge Driver for isolated power-supply circuits. The device contains an on-board oscillator, protection circuitry and internal FET drivers to provide up to 3W of power to the primary winding of a transformer. This can be operated using the internal programmable oscillator or can be driven by an external clock for improved EMI performance. Regardless of the clock source being used, an internal flip-flop stage guarantees a fixed 50% duty cycle to prevent DC current flow in the transformer. It operates from a single-supply voltage of +5 or +3.3V and includes under voltage lockout for controlled start-up. The device prevents cross-conduction of the H-bridge MOSFETs by implementing break-before-make switching. Thermal shutdown circuitry provides additional protection against damage due to over temperature conditions.
