FEATURES
Up to 92% Efficiency. Low Start-Up Voltage: 0.8V Internal Synchronous Rectifier Up to 100KHz Switching Allows Tiny External Components 2.5V to 5V Output Range (Note 3) Fully Discharged Shutdown Output Voltage Logic Controlled Shutdown (<1μA) Pulse Skipping at Light Load for Extended Battery Life Generates 3.3V at 20mA from Single AA Cell Stable with Ceramic Output Capacitor 6L SOT-26 Package
DESCRIPTION
The PS0020 is a synchronous, step-up DC/DC converter delivering high efficiency in a 6-leads SOT-26 package. The device having an internal NMOS switch and PMOS synchronous rectifier has the capacity of supplying 3.3V at 20mA from a single AA cell input. A high frequency switching minimizes board area by allowing the use of tiny, low profile inductors and ceramic capacitors. The PS0020 provides automatic pulse skipping at light loads reducing supply current for extended battery life. At shutdown the PS0020 fully discharges the output to ground and takes very low supply current. The PS0020 is available in small SOT26 package with both fixed and adjustable output voltage versions.
