SI-8000JDseries is a chopper type switching regulator IC, incorporating various features and protection functions needed for a step-down switching regulator.Switching regulator with high precision and high efficiency can be constructed with only 4 discrete components.
Feature
- Compact size and large output current of 1.5A TO-263-5 surface mount package, with maximum output current of 1.5A.
- High efficiency: 82%(SI-8050JD Vin=20V/Io=0.5A) Heat dissipation is small due to high efficiency to allow for the downsizing of a heat sink.
- Requires only 4 discrete components The regulator can be composed of input / output capacitor, diode and coil.
- Internally-adjusted phase correction and output voltage Troublesome adjustment of output voltage and phase compensation by means of external components is no longer required.
- Reference oscillation by a built-in timing capacitor No external capacitor for setting the oscillation frequency is required.
- Built-in functions for overcurrent and thermal shutdown Built-in foldback-overcurrent and thermal protection circuits (automatic recovery type)
- Output ON/OFF function(rise time delay setting can be made.) Output ON/OFF available, with low power consumption during OFF It is possible to delay the rising speed of output voltage at start-up by adding external capacitors.
Applications
- On-board local power supply
- Power supply for OA equipment
- For stabilization of the secondary-side output voltage of regulators
- Power supply for telecommunication
