RS6651 Efficient Synchronous Step-Up Converter with a 2.7A Switch 1 FEATURES 3 DESCRIPTIONS • Input Voltage Range: 2.2V to 4.5V • Up to 90% Efficiency at Typical Operating Conditions • Quiescent Current: 20μA (TYP) • • Less than 1μA Shutdown Current Adjustable Output Voltage Up to 5.5V • Power-Save Mode for Improved Efficiency at Low Output Power • Low Reverse Leakage Current when VOUT > VIN • Load Disconnect During Shutdown • Output short circuit protection • • Thermal shutdown protection Internal 1.5ms soft start time • Operating Temperature Range: -40°C to +85°C Micro SIZE PACKAGE: TSOT23-6 • The RS6651 is an internally compensated, 1.1MHz switching frequency, current mode, synchronous step-up switching regulator, which can generate 5V output at 1A load current from a 3.3V rail. This device turns into power-saving mode to maintain high efficiency by lowering switching frequency. With its antiringing circuitry damping the charge in parasitic capacitor, it reduces EMI interference significantly. Its output is disconnected by the rectifier circuit during shutdown, with no input to output leakage. RS6651-ADJ is output voltage programmable with an external resistor divider. When the RS6651 is in shutdown mode, the isolation switch disconnects the output from input to minimize the leakage current. The RS6651 also implements output short circuit protection, output overvoltage protection, and thermal shutdown. The RS6651 is available in Green TSOT23-6 package. It operates over an ambient temperature range of -40°C to +85°C. 2 APPLICATIONS • • Portable Audio Players • • Cellular Phones Device Information (1) Single-Cell Li-Ion Powered Products PART NUMBER PACKAGE BODY SIZE(NOM) RS6651 TSOT23-6(6) 2.92mm×1.60mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
