XC6209Series OPERATIONAL EXPLANATIONOutput voltage control with the XC6209 series:The voltage divided by resistors R1 & R2 is compared with the internalreference voltage by the error amplifier.The P-channel MOSFET, which is connected to the VOUT pin, is thendriven by the subsequent output signal. The output voltage at the VOUTpin is controlled & stabilized by a system of negative feedback.The current limit circuit and short protect circuit operate in relation tothe level of output current. Further, the IC's internal circuitry can beshutdown via the CE pin's signal. Low ESR Capacitors With the XC6209 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase compensationcircuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) isconnected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output capacitor with a capacitancevalue of at least 1μF. Also, please connect an input capacitor (CIN) of 1μF between the VIN pin and the VSS pin in order toensure a stable power input.Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias andtemperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can ensure theactual capacitance. Current Limiter, Short-Circuit Protection The XC6209 series includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of thecurrent limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuitoperates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltagedrops further and output current decreases. When the output pin is shorted, a current of about 50mA flows. CE Pin The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6209 series. In shutdown mode, outputat the VOUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is selectable (pleaserefer to the selection guide). Note that as the standard XC6209B type is ' Active High /No Pull Down', operations will becomeunstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS hysteresis, with either the pull-upor pull-down options, the CE pin input current will increase when the IC’s in operation.We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with thecorrect specifications for the CE pin, the IC will operate normally. However, supply current may increase as a result of throughcurrent in the IC's internal circuitry NOTES ON USE1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratingsbe exceeded.2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current.Please strengthen VIN and VSS wiring in particular.3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible.4. The IC is controlled with constant current start-up. Start-up sequence control is requested to draw a load current after evennominal output voltage rising up the output voltage.5.
