TS3300ITQ1633T

TS3300 0.6-3VIN, 1.8-3.6VOUT, 3.5µA, High-Efficiency Boost + Output Load Switch FEATURES DESCRIPTION  The TS3300 is a 1st-generation power management product that combines a high-efficiency boost regulator and an output load switch in one package. The boost regulator operates from a supply voltage as low as 0.6V and can deliver at least 75mA at 1.2VBI to 3VBO, an industry first.     Combines Low-power Boost + Output Load Switch Boost Regulator  Input Voltage: 0.6V- 3V  Output Voltage: 1.8V- 3.6V  Efficiency: Up to 84%  No-load Input Current: 3.5µA  Delivers >100mA at 1.8VBO from 1.2VBI  Boost Shutdown Control  No External Schottky Diode Required Anti-Crush Capability  Prevents Input Voltage Collapse when powered with Weak/High Impedance Power Sources Single-Inductor, Discontinuous Conduction Mode Scheme with Automatic Peak Current Adjustment 16-Pin, Low-Profile, Thermally-Enhanced 3mm x 3mm TQFN Package APPLICATIONS Coin Cell-Powered Portable Equipment Single Cell Li-ion or Alkaline Powered Equipment Solar or Mechanical Energy Harvesting Wireless Microphones Wireless Remote Sensors RFID Tags Blood Glucose Meters Personal Health-Monitoring Devices The TS3300 includes an anti-crushTM feature to prevent the collapse of the input voltage to the boost regulator when the input is a weak (high impedance) source. If the input voltage drops below a determined voltage threshold (settable by a resistor divider), the boost regulator switching cycles are paused, effectively limiting the minimum input voltage. AnticrushTM is useful in applications where a buffer capacitor at the boost’s output can service burst loads, and the input source exhibits substantial source impedance (such as an old battery, or at cold temperatures). The TS3300 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, thermally-enhanced 16-pin 3x3mm TQFN package with an exposed back-side paddle. For best performance, solder the exposed back-side paddle to PCB ground.
