製品説明

The EVHFC0500+MP6902+MP5017-00AEvaluation Board is mainly designed to demonstrate the capabilities of MPS flyback controller and secondary synchronous rectifier (SR) driver. The HFC0500 is a full-featured flyback controller aims at high-performance and high-integration solution while MP6902 is a secondary synchronous rectifier driver, which can promote converter efficiency observably. MP5017 is a current limiter to protect circuit.

The EVHFC0500+MP6902+MP5017-00A is typically designed for cell phone charger with 4 USB ports, each port has 2.4A source capability and  input is from 85VAC to 265VAC, 50HZ/60HZ.

The EVHFC0500+MP6902+MP5017-00A has excellent efficiency, which can meet CoC V5 and DoE Level Ⅵ requirement easily. It meets IEC61000-4-5 surge immunity and EN55022 conducted EMI requirements. It has multi-protection function, e.g., Brown In/Out, over load protection, over voltage protection, short-circuit protection, cycle by cycle current limit and over-temperature protection, etc.

パラメータ


Fixed Frequency Flyback Controller with Ultra-low No Load Power Consumption

HFC0500 is a fixed-frequency current-mode controller with internal slope compensation. It is specifically designed for the medium-power, off-line, flyback, switch-mode power supplies. HFC0500 is a green-mode highly efficient controller. At light loads, the controller freezes the peak current and reduces its switching frequency down to 25kHz to offer excellent light-load efficiency. At very light loads, the controller enters burst mode to achieve very low standby power consumption. HFC0500 offers frequency jittering to help dissipate energy generated by conducted noise. HFC0500 employs overpower compensation function to narrow the difference of over power protection point between low line and high line. HFC0500 also has X-cap discharge function to discharge the X-cap when the input is unplugged. This aids in lowering no load power. HFC0500 features multiple protections that include thermal shutdown (TSD), VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and brown-out protection. HFC0500 is available in an SOIC8-7A package.


3V-5.5V, 1A-5A Current Limit Switch with Over-Voltage Clamp and Reverse Blocking

The MP5017 is a protection device designed to protect circuitry on the output from transients from the input. Also, it protects the input from unwanted shorts and transients coming from the output.
During start-up, the inrush current is controlled by limiting the slew rate at the output. The slew rate is controlled with a small capacitor at DV/DT.
The maximum load at the output is current limited. The magnitude of the current limit is controlled by an external resistor from ILIMIT to GND. By controlling the gate voltages with a pair of N-channel MOSFETs, any current flowing from the output to the input is blocked.
Under-voltage lockout (UVLO) ensures that the input is above the minimum operating threshold before the power device is turned on. If the input voltage rises above 5.8V, the output voltage is limited quickly to 5.8V. SAS/OV is used to program the input over-voltage protection threshold.
is an open-drain output that reports a fail mode (low level) when any over-current, over-temperature, or output over-voltage is detected.
The MP5017 is available in a QFN-12 (2mmx3mm) package.
