qSPI-8000A Series
SPI-8000A Series
Surface-mount, Separate Excitation Switching Type
sFeatures
· · · · · Surface-mount 16 pin package Output current: 3.0 A High efficiency: 91% (at VIN = 10 V, lO = 1 A, VO = 5 V) High operating efficiency of 250 kHz allows reduction of choke coil. A 1 V reference voltage (Vref) of variable output voltage type can support output voltage from 1 V to 24 V. · Wide Input Voltage Range (8 to 50 V) · Output ON/OFF capable · Built-in overcurrent protection and thermal protection circuit
sApplications
· Onboard local power supplies · OA equipment · For stabilization of the secondary stage output voltage of switching power supplies

*3: Reference voltage temperature coeficient for SPI-8010A *4: VREF/Ta for SPI-8010A
*5: No. 2 terminal is a CE/SS terminal to enable soft start by connecting a capacitor. The output can be turned on and off by using a CE/SS terminal. The output is stopped by decreasing the CE/SS terminal voltage below VSSL and in order to perform ON/OFF operation of VOUT, it is required to connected NPN transistor or the output of open collector type TTL between No. 5 terminal and GND. In case that both soft start and VOUT ON/OFF are used, a protection measure such as limitation of current is required, as the discharge current of C4 flows across a transistor for ON/OFF operation, if the capacitance of C4 large. As a pull-up type resistor is provided inside the IC, no external voltage can be applied.

sApplication Notes
Parallel Operation: The parallel operation to increase the current is not available. Thermal Protection Characteristics: The SPI-8000A series has a thermal protection circuit. This circuit keeps the IC from the fever by the over load. But this circuit cannot guarantee the long-term reliability against the continuously over load status.
sHandling Remarks to Prevent Damage by Static Electricity
Considerations to protect the Products from Electrostatic Discharge · When handling the devices, operator must be grounded. Grounded wrist straps be worn and should have at least 1 M of resistance near operators to ground to prevent shock hazard. · Workbenches where the devices are handled should be grounded and be provided with conductive table and floor mats. · When using measuring equipment such as a curve tracer, the equipment should also be grounded. · When soldering the devices, the head of a soldering iron or a solder bath must be grounded in other to prevent leak voltage generated by them being applied to the devices. · The devices should always be stored and transported in our shipping containers or conductive containers, or be wrapped up in aluminum foil.
