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 ICs 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

■ Applications
• Power supplies for telecommunication equipment
• Onboard local power supplies
