HP1016: Low-power single-phase CrM PFC controller chip officially released

In applications with output power ranging from 100 to 300W, covering consumer electronics, household appliances, LED lighting, and communication equipment, traditional flyback architectures are increasingly unable to meet the high switching frequency, high power density, and high efficiency requirements of modern high-power applications. Power factor correction (PFC) is needed. For power systems at this power level, single-phase critical mode (CrM) PFC controllers have demonstrated their unique advantages. They not only effectively improve the overall efficiency of the system, but also ensure a higher power density in a compact design space, thereby better meeting the current market demand for high-performance power supply solutions.

HP1016 is the latest power factor correction (PFC) constant voltage conversion mode boost controller launched by HuiNengTai. It adopts constant on-time control to achieve high PF and low THD without line voltage detection. HP1016 can work in CrM/DCM mode to achieve high efficiency and better EMI performance. It is designed with special features for fast startup and reliable protection to meet safety requirements.

Application Scenarios

The HP1016 can be widely used in AC-DC power adapters, LED drivers, industrial power supplies, and other applications where low power consumption is required but high efficiency and reliability are essential. Its compact design and excellent performance make it a leader in these fields. It is also suitable for applications requiring high power factor correction and stable output such as two-wheeler chargers, high power UPS, etc. The PFC design achieves full-voltage high PF / low THD performance, ensuring power supply stability and efficiency.

Compact Package

The HP1016 is available in a SOT23-6 package that is small and highly integrated for easy layout on compact PCB boards. In terms of functional substitutability, the HP1016 demonstrates the ability to seamlessly integrate with similar products such as the ✱✱5072B, realizing “painless substitution”. This means that the HP1016 can be directly upgraded without significant modification or redesign of existing circuits, reducing the additional cost and time associated with design changes, while maintaining system performance stability and consistency.

Low Standby Power Consumption

The HP1016 has a very low quiescent current of as low as 0.4mA, and light no-load adaptive operation in Burst mode enables the system to have very low standby power consumption.

High Performance

Critical mode operation (CrM) means that it maintains high efficiency while optimizing the switching strategy to reduce power consumption. No auxiliary winding enables ZCD detection, QR valley conduction, and reduced switching losses, which not only improves overall efficiency, but also optimizes EMI (Electromagnetic Interference) performance for a more compact and reliable design.

With built-in THD compensation, the HP1016 eliminates the effect of negative current under CrM operation, easily realizing high power factor (PF) and low input harmonic distortion (THD) over the full voltage range, bringing excellent performance to the system.

Multi-protection

The chip has built-in rich protection functions, such as over-voltage protection, over-current protection, and over-heat protection, to ensure the stable operation of the system. These protection functions can respond quickly in abnormal situations to prevent damage and protect user equipment.
