The PT4110 is a high efficiency step-up DC/DC converter designed for driving multiple strings of up to eight series-connected white LED from a single cell Lithium Ion battery. It regulates the output current, ideal for driving light emitting diodes (LED) whose light intensity is proportional to the current passing through them. The external ballast resistor .
to protect itself from fault conditions including built-in open load protection, cycle-by-cycle current limit, over temperature shutdown, input under voltage control and integrated soft-start. The PT4110 is available in SOT-89-5 and SOP-8 packages. FEATURES z z z z z z z z z z z 2.7V to 5.5V Input Voltage Range 35V Maximum Step-Up Voltage <1µA Shutdown Mode 1.2MHz Fixed Frequency Operation Cycle-By-Cycle Current Limit Open Load Protection Under Voltage Lockout Integrated Soft-Start Thermal Shutdown Frequency Jittering for better EMI performance SOT89-5 or SOP8 package APPLICATIONS z z z z z .
