MP100 – OFFLINE INDUCTOR-LESS REGULATOR MP100 Rev. 1.04 www.MonolithicPower.com 8 1/23/2014 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2014 MPS. All Rights Reserved. OPERATION MP100 employs a smart inductor-less regulator design (patent pending) to charge the VD capacitor (C1 in Figure 4) from the offline AC input, and then to deliver the stored energy to the load with a stable output voltage. When VIN is less than its 35V threshold, VD can be charged up by up to 1.8A input current. An internal LDO regulates VOUT to 12V and can supply up to 10mA load when VIN is between 85VAC and 305VAC. The proprietary design allows the universal AC input to efficiently power the IC directly. Startup During the startup, the internal switch connected between VIN and VB turns on when the input voltage is within its charging window (typically below 35V), thus gradually charging the VD voltage. The LDO will not resume with a soft- start until the VD voltage reaches 15.3V. Active Bleeder Circuit The input voltage may not enter its charging window during normal operation due to parasitic capacitance from VIN to GND. An active bleeder circuit is enabled to pull down the VIN voltage whenever the VD voltage falls below 14V to guarantee that the output gets enough energy from the input ports. In addition, when the power supply shuts down, the active bleeder circuit discharges the energy stored in the parasitic capacitor to ensure that the circuit can restart easily. VD Over-Voltage Protection The VD capacitor provides energy for the output load. If the voltage of VD exceeds 30V, the internal switch between VIN and VB turns off immediately to prevent the VD voltage from rising too high, which can damage the LDO stage. Short-Circuit Protection The output current is limited to 150mA if the output is shorted to ground, which also decreases the VD voltage. When VD drops below 6.8V, LDO turns off. The input voltage then gradually charges VD up to 15.3V to enable the LDO. When LDO turns on, the output current drops the VD voltage to 6.8V again. This process will continue until the output short condition ceases. Over-Current Protection The VD and VOUT voltages will drop simultaneously if the output current exceeds its normal value. When the VD voltage falls to 6.8V, the second stage LDO shuts down immediately. Then the input voltage charges VD to 15.3V to enable the LDO. Due to the output current limit circuit, the maximum current is typically limited to 150mA. Thermal Shutdown Protection Accurate temperature protection prevents the chip from operating at exceedingly high temperatures. When the silicon die temperature exceeds 160°C, the whole chip shuts down. When the temperature falls below its lower threshold of 140°C, the chip is enabled again. Power-Good The MP100 integrates a power-good circuit to signal that the output meets the controller IC’s requirements. It is an open drain structure and requires a pull-up resistor to VOUT. During start up, the VOUT voltage rises smoothly. When it reaches 80% of its normal value, the power-good signal goes high after a 200µs delay to indicate a normal output.

The maximum output capability can be roughly estimated by following equation: +× π ×× × VD peak line THVIN DMIN o o_m a x peak vd in line 2C I f ( V V )VP I2 2 C V f Where, VDC ( F) is the capacitance connected to VD; peakI (A) is the input peak current at full load, which can be estimated by following equation: =− ×peak DMINI 1.25 0.036 V ; linef (Hz) is the rectified line frequency; THVINV (V) is the input voltage threshold to shut down the internal switch connected between VIN and VB, typically it is 35V; DMINV (V) is the minimum voltage of VD to maintain the output voltage, usually; it can be got by following equation: oD MIN DMIN DMIN V1i f V 6 . 8 VV 6.8V if V 6.8V oV (V) is the output voltage; inV (V) is the RMS value of input voltage; To get more output power, MP100 can be paralleled. Figure 6 shows how it is implemented. More MP100 can be paralleled in the same way to get the output power need. Another way to get more output power is using an external MOSFET to charge the capacitor connected between VD and GND. Figure 7 shows an example. To prevent the thermal damage of external MOS when VD is shorted to GND directly, PTC (Positive Temperature Coefficient) is used which should be placed as close as to the external MOS to detect the temperature. When the temperature of external MOS reaches certain value, the resistor of PTC will increase sharply to pull down the gate voltage and shut down the external MOS. To guarantee its normal start up and steady state operation, R3/R2 should be more than 4.5. At the same time, R3/R2 should not be too high to get better thermal protection; generally it should be less than 10. R1 can be used to adjust the switch speed of external MOS. Line Transformer MP100 can work well when connected to AC line or programmable AC source. But when using an isolation transformer or a variable transformer as source, because of the high inductance of the transformer (usually in the mH’s), high voltage spikes occur when MP100 turns off the internal switch connected between VIN and VB, which may damage the IC. An X- capacitor must be installed before the rectifier to guarantee the reliability of the system. EMI An appropriate X-capacitor should be connected between the input ports to guarantee the circuit can meet EMI requirements. Figure 3 shows the recommended X-capacitor values to pass EMI in different applications. 0.22 0.22 0.47 0.68 0.22 0.22 0.22 0.2 0.4 0.6 0.8 1.2 1.4 0 5 10 15 20 25 0.2 0.4 0.6 0.8 0 2.5 5 7.5 10 12.5 0.22 0.22 0.22 0.22 0.22 0.33 0.22 0.47 Figure 3: X Cap Value Required in Different Application
