SI-8120JF

1-1-3 DC/DC Converter ICs SI-8000JF Series Full-Mold, Separate Excitation Step-down Switching Mode ■Features Compact full-mold package (equivalent to TO220) Output current: 1.5A High efficiency: 67 to 88% Requires only 4 discrete components Internally-adjusted phase correction and output voltage Capable of downsize a choke-coil due to IC's high switching frequency (125kHz). (Compared with conventional Sanken devices) Built-in foldback-overcurrent and thermal protection circuits Output ON/OFF available (circuit current at output OFF: 200µA max.) Soft start available by ON/OFF pin ■Lineup Part Number VO (V)* IO (A) * VREF(V) for SI-8015JF SI-8015JF 1.59 ■Absolute Maximum Ratings Parameter DC Input Voltage Power Dissipation Junction Temperature Storage Temperature Thermal Resistance (Junction to Case) Symbol VIN PD1 PD2 Tj Tstg θj-c SI-8033JF 3.3 1.5 SI-8050JF 5.0 Ratings 43 16.6 (with infinite heatsink) 1.5 (without heatsink, standalone operation) +125 –40 to +125 6.0 SI-8120JF 12.0 Unit V W W °C °C °C/W ■Applications Power supplies for telecommunication equipment Onboard local power supplies ■Recommended Operating Conditions Parameter DC Input Voltage Range Output Current Range Operating Junction Temperature Range Symbol VIN1 VIN2 IO Tjop SI-8015JF* VO+2 to 40 VO+3 to 40 Ratings SI-8033JF SI-8050JF 5.3 to 40 7 to 40 6.3 to 40 8 to 40 0 to 1.5 –30 to +125 SI-8120JF 14 to 40 15 to 40 Unit V V A °C Conditions IO=0 to 1A IO=0 to 1...
