n Two Independent Step-Up Converters n Each Channel Delivers 3.3V at 100mA from a Single Alkaline/NiMH Cell or 3.3V at 200mA from Two Cells n VIN Start-Up Voltage: 680mV n 1.5V to 5.25V VOUT Range n Up to 94% Efficiency n Output Disconnect n 1MHz Fixed Frequency Operation n VIN > VOUT Operation n Integrated Soft-Start n Current Mode Control with Internal Compensation n Burst Mode® Operation with 9µA IQ Each Channel n Internal Synchronous Rectifier n Logic Controlled Shutdown (IQ < 1µA) n Anti-Ring Control n Low Profile (3mm × 3mm × 0.75mm) 12-Lead DFN Package APPLICATIONS n Medical Instruments n Noise Canceling Headphones n Energy Harvesting n Bluetooth Headsets The LTC®3535 is a dual channel, synchronous, fixed frequency step-up DC/DC converter with output disconnect.
Extended battery life in single AA/AAA powered products is realized with a 680mV start-up voltage and operation down to 500mV once started.
A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors.
