Description

The RX6C is an electronic component model in the IC Chips category. It belongs to the STR-X6700 series of power ICs for quasi-resonant type switching power supplies. This product is designed to achieve high efficiency and low noise power supply systems through its quasi-resonant operation and bottom-skip quasi-resonant operation. It is also available in different package versions as part of the STR-W6700 series.

Specifications and features

- Multi-Mode Control: The RX6C features operation mode switching with three steps according to load conditions, resulting in optimal high efficiency and low noise power supply systems across the full load range.

- Current-Mode Control

- Built-in PWM Oscillator: The PWM operates with a minimum frequency of around 22 kHz, reducing the stress on components at startup and load-shorted.

- Soft-Start Function

- Step-Drive Function, reducing switching noise

- Built-in Maximum ON Time Limitation Circuit: This function limits the maximum ON time of the power MOSFET during transitions at low input voltage and power ON/OFF.

- Input Compensation at Overcurrent: The RX6C reduces the distortion of the overcurrent operation point to AC input voltage change by adding three components.

- Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET

- Various Protections: Overcurrent Protection (OCP), Overload Protection (OLP), and Overvoltage Protection (OVP)

Application Scenarios

The RX6C is widely used in switching power supplies for digital consumer equipment such as LCD-TVs, PDP-TVs, CRT-TVs, home appliances, OA equipments, industry machines, communication devices, and others.
