HT77XX規(guī)格書詳情
General Description
The HT77XX series is a set of PFM step-up DC/DC con verter with high efficiency and low ripple. The series features extremely low start-up voltage and high output voltage accuracy. They require only three external components to provide a fixed output voltage of 1.8V, 2.2V, 2.7V, 3.0V, 3.3V, 3.7V or 5.0V. CMOS technology ensures ultra low supply current and makes them ideal for battery-operated applications powered from one or more cells.
Features
? Low start-up voltage: 0.7V (Typ.), 0.9V (Max.)
? High efficiency: 85 (Typ.), VOUT ≥ 2.7V
? High output voltage accuracy: ±2.5
? Output voltage: 1.8V, 2.2V, 2.7V, 3.0V, 3.3V, 3.7V, 5.0V
? Output current up to 100mA
? Ultra low supply current IDD2: 4μA (Typ.)
? Low ripple and low noise
? Low shutdown current: 0.5μA (Typ.)
? TO92, SOT89, SOT23 and SOT23-5 package
Applications
? Palmtops/PDAs
? Portable communicators/Smartphones
? Cameras/Camcorders
? Battery-powered equipment
