Description

SI-8000JD series 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.

Application

・Power supply for telecommunication equipment
・On-board local power supply

Features

・Surface-mount(TO263-5) package
・Output current: :1.5A
・High efficiency: 77~88%
・4 external components
・Internally-adjusted phase compensation and output voltage
・Capable of downsizing a choke-coil due to the IC's high switching frequency (Compared with conventional Sanken devices)
・Built-in foldback-overcurrent and thermal protection circuits
・Output ON/OFF available (circuit current at output OFF: 200μAmax)
・Soft start available by ON/OFF
