HLD15ZEB

DC-DC converters are devices used in electronic systems to change the level of voltages used. They are a common requirement in mixed-voltage applications where a higher voltages are required from the lower voltages provided by the power supply. The HLD15ZEB is a power converter with an industrial-standard 15 amp continuous current rating. It is designed for general purpose power applications in the automotive, power supply and entertainment industry.

HLD15ZEB Application Field and Working Principle

The HLD15ZEB is a DC-DC converter which is commonly used in the automotive, power supply and entertainment industry due to its industrial-standard 15 amp continuous current rating. It can also be used in high current applications as it has high-current switching capability. It is also designed to support the latest environmental regulations, as it has lower power consumption and improved thermal dissipation.

The HLD15ZEB uses a high-intelligent power IC, the ISL75203, which executes the current detection, pre-charge, and PFC control functions.

Current Detection Function

The current detection function is used to monitor the output current, and if it exceeds the preset limit, the controller can automatically shut down the circuit, preventing any damage to the system components.

Pre-Charge Function

The pre-charge function is an important part of circuit protection, and is important for ensuring the system is properly charged before operating. The pre-charge is enabled when the input voltage is below a preset level, and soft-starts the system when the voltage is above the pre-charge point.

PFC Control Function

The PFC control function ensures the output current is at the optimum level and helps reduce current harmonics and power losses. It also prevents voltage spikes and drops, increasing the reliability of the system.

The benefits of using the HLD15ZEB in these applications are the reliable power supply and improved efficiency. The built-in protection functions also ensure the circuit will not be damaged due to overcurrent or voltage. Additionally, it is designed to meet the latest environmental regulations which requires lower power consumption and better thermal dissipation.
