The MAX256ASA+ by Analog Devices is an integrated primary-side controller and H-bridge driver for isolated power supply circuits. This device is capable of delivering up to 3W of power to the primary winding of a transformer. It operates from a single supply voltage of +5V or +3.3V and includes essential protection features such as undervoltage lockout and thermal shutdown circuitry.
The MAX256ASA+ offers flexibility with an internal programmable oscillator or an external clock input for improved EMI performance. It guarantees a fixed 50% duty cycle to prevent DC current flow in the transformer. The device also implements break-before-make switching to prevent cross-conduction of the H-bridge MOSFETs.
This driver is available in an 8-pin thermally-enhanced SO package (SOIC-EP) and is specified for the automotive temperature range of -40°C to +125°C. Its applications include isolated power supplies, industrial process control, isolated communications links, medical equipment, and telecommunications.
Key electrical characteristics include a supply voltage range of 3V to 5.5V, a current rating of 1A, and an on-resistance of 500mOhm (typical). The mounting type is surface mount.
