1 / 10 page  www.SiliconStandard.com 1 of 10 SS6563 Versatile DC/DC Converter FEATURES Operates from 3V to 30V input voltage Internal 2A peak current switch. Continuous output current of 1.5A Bootstrapped driver. High-side current sense capability. High efficiency (up to 90%). Internal ±2% reference. Low quiescent current at 1.6mA. Operating frequency from 100Hz to 100KHz. APPLICATIONS Constant Current Source for Battery Chargers. Saver for Cellular phones. Step-Down DC/DC Converter Module. DESCRIPTION The SS6563 is a monolithic control circuit that provides the primary functions required for DC to DC converters and high-side-sensed constant current sources. The device consists of an inter- nal temperature compensated reference, com- parator, controlled duty-cycle oscillator with an active current-sense circuit, bootstrapped driver, and high-current output switch. This device is specifically designed to construct a constant cur- rent source for battery chargers with a minimum number of external components. A bootstrapped driver can drive the NPN output switch to satura- tion for higher efficiency and less heat dissipation. The SS6563 can deliver 1.5A continuous current without requiring a heat sink.
