V7806-1500

a d ivision of CUI INC date 07/2010 page 1 of 5 SERIES: V78XX-1500 DESCRIPTION: DC SWITCHING REGULATOR, NON-ISOLATED DESCRIPTION The V78XX switching regulator series is designed to be a high efficiency drop-in replacement for 78XX linear regulators. Unlike linear regulators, the V78XX series does not require a heatsink, creating a much more compact solution. Built-in short-circuit and over-temperature protections ensure very rugged operations. Additionally, low ripple and noise performance make the parts useful in a wide range of applications. FEATURES •efficiency up to 95% •1.5A current output •operating temp: -40 ~ +85°C •short circuit protection •thermal shutdown •low ripple and noise •miniature SIP package, meets UL94-V0 requirement •ultra low power loss •negative output capacity •pin compatible to LM78XX series •MTBF >2,000,000 hours RoHS efficiency level Vin (min) Vin (max) MODEL V7802-1500 V7803-1500 V7805-1500 V7806-1500 input voltage min (V dc) max (V dc) output voltage max (V dc) output current max.

C1 and C2 are required and should be fitted close to the converter pins. 2. The capacitance of C1and C2 sees external capacitor table, it can be increased properly if required, and tantalum or low ESR electrolytic capacitors may also suffice. 3. No parallel connection or plug and play. 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382 www.v-infinity.com a d ivision of CUI INC date 07/2010 page 4 of 5 SERIES: V78XX-1500 DESCRIPTION: DC SWITCHING REGULATOR, NON-ISOLATED INPUT FILTER CIRCUIT 1 0 u H-4 7 u H Vin 10uF 10uF Vin Vo Vout GND GND GND OUTPUT FILTER CIRCUIT 1 0 u H-4 7 u H Vin 10uF Vin Vo 10uF 22uF RL GND GND EMC RECOMMENDED CIRCUIT Vin 330 uF 1 mH Vin 2.2 uF 1u F Vo Vout GND GND 1mH GND 20050 SW 112th Ave. Tualatin, Oregon 97062 phone 503.612.2300 fax 503.612.2382 www.v-infinity.com a d ivision of CUI INC date 07/2010 page 5 of 5 SERIES: V78XX-1500 DESCRIPTION: DC SWITCHING REGULATOR, NON-ISOLATED TEST CONFIGURATION Efficiency and Output Voltage Ripple Test Vin 25. 4m m 25.4mm 12.7mm 1 C1 D C /D C C onverter 2 3 C2 Copper strip 1F 10 F +Vout 2.54 mm 2.54 mm Ceramic Tantalum Scope GND Copper stri p Start-up and Load Transient Response Test Vin 50.8 m m 1 C1 D C /D C C onverter 2 3 C2 Copper strip +Vou t Scope GND Copper strip EFFICIENCY AND RIPPLE CURVES Efficiency Efficiency VS.
