DESCRIPTION
The ZXSC300 is a single or multi cell LED driver designed for applications where step-up voltage conversion from very low input voltages is required. These applications mainly operate from single 1.5V or 1.2V battery cells. The circuit generates constant current pulses that are ideal for driving single or multiple LED’s over a wide range of operating voltages.

FEATURES
• 94% efficiency
• Minimum operating input voltage 0.8V
• Fixed output current
• Low saturation voltage switching transistor
• SOT23-5 package
