Описание:

В базовом проекте PMP10116 используется контроллер ККМ в переходном режиме UCC28063A для управления LED’ами с током до 700 мА и входом по переменному току. Данная топология ККМ с обратноходовым преобразователем подразумевает гальваническую развязку и задействует управление в квазирезонансном режиме. В проекте поддерживается аналоговый димминг на выходной стороне. Инструкцию к проекту вы можете найти тут: LED-драйвер на базе однокаскадного обратноходового AC/DC-преобразователя UCC28060.

The PMP20795 reference design uses UCC256301 enhanced LLC controller with integrated driver to provide 24V/12A output from a nominal 380VDC input. UCC256301 provides hybrid hysteresis control (HHC) to enable a fast transient response. In this design, a 1st order system with over 6kHz bandwidth is achieved. In addition, the advanced burst mode allows this converter to achieve less than 200mW power consumption at no load. With 200kHz nominal switching frequency, the converter is able to achieve over 96% peak efficiency.
Возможности:

380VDC input to 24V/12A output Board height less than 15mm Less than 200mW standby power consumption Over 96% peak efficiency

The PMP21098 reference design uses UCC28056 transition mode PFC controller and UCC25630 enhanced LLC controller with integrated driver to provide 12V/10.8A output (continuous, 14.2A peak) from universal AC input. This design achieves 92.4% peak efficiency at 115VAC input and 94% peak efficiency at 230VAC input. The efficiency and power factor numbers also meet both 115V and 230V internal 80 PLUS gold specifications. In addition, the design is able to achieve less than 600mW power consumption with 350mW output power without turning off PFC.

The PMP9730 reference designemploys the UCC28051 power factor correction controller to implement a single stage PFC-Flyback AC/DC converter that generates an isolated 12V output at 3A from a universal AC input. The design features UCC28910 primary side regulation Flyback switcher for generating the VDD bias rails and the UCC24610 for 2ndary side synchronous rectification. This provides an excellent solution for systems such as motor drives requiring an isolated bus voltage, good power factor and high efficiency.

Возможности:

89% 4-pt average efficiency 90% peak efficiency >0.85 Power factor at 100% load No aluminum capacitors for small size and high reliability Small form factor 50mm X 50mm x 18mm (2" X 2" X 0.7")

The TIDA-01494 reference design is a compact, high efficiency, 24-V DC, 480-W nominal, 720-W peak output reference design for industrial AC/DC power supplies. The circuit consists of a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit followed by a robust LLC stage with synchronous rectification. The design enables efficiency greater than 93.5% over a wide load range, allowing the system to work without forced cooling. The LLC stage, based on the UCC256301, takes advantage of the ZCS avoidance feature in the UC256301 to enable peak output power, minimizing the PFC Bulk capacitor for meeting holdup requirements, while making the system robust to short circuit and over current conditions. The UCC24612-2 based synchronous rectifier helps in minimizing the losses in the output rectifier, while its advanced proportional gate drive and dead time optimization features helps to avoid shoot through and minimizes losses.
Возможности:

Peak power conversion efficiency of 94% at 230V AC with average efficiency >93.5% Delivers 20A continuous current and up to 30A peak current for 3 seconds Power factor >0.99 and meets PF and current THD as per IEC 61000-3-2 Class A and EN55022 Class B Conducted Emission standard ZCS avoidance in the LLC stage, enabling wider input voltage range operation and robustness Over current, short circuit, over voltage and over temperature protection Compact form-factor: 155mm x 125mm
