Enable Threshold Voltages vs. By topology, the maximum output voltage will be equal or lower than the input voltage. If the corner frequency is moved, it is recommended to check the loop stability depending of the accepted output ripple voltage and the required output current. In shutdown mode, the internal reference, oscillator and most of the control circuitries are turned off.

The capacitance needed for the input bypass capacitor depends on the source impedance of the input supply. Maximum Output current eq.

Maximum Ratings are stress ratings only. This feature is provided to prevent catastrophic failures from accidental device overheating. The peak inductor current depends upon the drop between input and output voltage. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. In this mode all power transistors and control circuits are turned off.

The pin must be connected to the system ground. When the voltage across the capacitor ramps up to the nominal reference voltage, c language library functions pdf the pulsed current source will be switched off and the reference voltage will switch to the regular reference voltage. Description Enable for switching regulators. The output regulation is implemented by pulse frequency modulation.

High Efficiency DC-DC Converters

Soft start is implemented by gradually increasing the reference voltage until it reaches the full reference voltage. It's a community-based project which helps to repair anything. There may be other patents pending. Selecting the proper output capacitor is based on the desired output ripple voltage.

Whole output voltage range is available for adjustable versions only. It uses synchronous rectification to increase efficiency and reduce external part count. Functional operation above the Recommended Operating Conditions is not implied.

Undervoltage Lockout Threshold vs. Take care to check the loop stability. The feed-forward capacitor sets the feedback loop response and acts on soft-start time. This literature is subject to all applicable copyright laws and is not for resale in any manner. The correct selection of the output filter ensures good stability and fast transient response.

Short Circuit Protection When the output is shorted to ground, the device limits the inductor current. Good layout is key to prevent switching regulators to generate noise to application and to themselves.
