LM3208TLEV is an evaluation board for DC/DC & AC/DC (Off-Line) Switch Mode Power Supplies (SMPS). It is a fully integrated off-line/DC-DC/AC-DC converter with a high single-stage efficiency over a wide input voltage range. LM3208TLEV features a wide 3.3V-25V input voltage range, 1A output current, under-voltage-lockout, thermal shutdown, and cycle-by-cycle current limit. It also provides ruggedness to prevent electrostatic discharge (ESD), over-current protection (OCP), and over-temperature protection (OTP).

The LM3208TLEV application field includes high-end consumer electronics, industrial applications, automotive electronics, medical equipment, communications, and wireless power systems. It is a suitable power solution for applications with a variety of input voltage requirements, such as AC/DC and DC/DC converters, DC/AC inverters, battery-powered systems, and voltage regulators. It is designed for wide input voltage range applications, such as telecom, automation, and factory automation.

The LM3208TLEV board offers several advantages over other off-line SMPS solutions:

• Fully integrated DC/DC/AC/DC control module: The evaluation board can be easily configured toselect either an AC/DC or a DC/DC converter with optimal efficiencies over a wide input voltage range
• High Single-Stage Efficiency: It reaches up to 93% efficiency in a wide input voltage range from 3.3V~25V
• Robust design: LM3208TLEV features cycle-by-cycle current limit, under-voltage lockout, over-temperatureprotectionsandElectrostaticDischargeprotections
• Wide input voltage range: LM3208TLEV has a wide operating range of 3.3V to 25V, which provides flexibility in design
• High output current capability: This board is capable of delivering 1A output current

The board consists of the following main components:

• Primary Control IC: LM3208TLEV includes a dedicated control IC, the LM3208T, specifically designed for off-linemode-switching power supplies. This provides a fully integrated single-stage architecture with high-performance over a wide input voltage range
• Power Switches: This board contains a pair of power MOSFETs, one P-Channel and one N-Channel, forming an inverting-H-bridge, which is used for power switching. The P-Channel MOSFETs are rated for up to 30V and the N-Channel MOSFETs are rated for up to 60V.
• External components: The board also includes several external components such as inductor, output capacitor, and Schottky diode.
• Input capacitor and rectifier: An input capacitor is placed at the VIN input for filtering and an external rectifier is placed at the VOUT output to improve efficiency.

The LM3208TLEV board works by switching power to the output through an inverting-H-bridge circuit. The control IC, LM3208T, monitors VIN and VOUT voltages and controls the power switches at optimal switching frequency. The output current is limited by the external MOSFETs. The board also features protections such as over-temperature, under-voltage lockout, and electrostatic discharge. The board requires the user to provide a bias voltage of 3.3V to enable the IC and the MOSFETs.

The LM3208TLEV board is a fully integrated off-line/DC-DC/AC-DC converter and offers high single-stage efficiency, ruggedness, and robust protection for a wide input voltage range. It is suitable for applications in high-end consumer electronics, industrial applications, automotive electronics, medical equipment, communications, and wireless power systems.
