HT7730SA规格书详情
General Description
The HT77xxSA devices are a high efficiency PFM synchronous step-up DC-DC converter series which are designed to operate with both wire wound chip power inductors and also with multi-layered chip power inductors. The device series have the advantages of extremely low start-up voltage as well as high output voltage accuracy. Being manufactured using CMOS technology ensures ultra low supply current. Because of their higher operating frequency, up to 500 kHz, the devices have the benefits of requiring smaller outline type lower value external inductors and capacitors. The higher operating frequency also offers the advantages of much reduced audio frequency noise. The devices require only three external components to provide a fixed output voltage of 2.7V, 3.0V, 3.3V, 3.7V or 5.0V.
Features
• Low start-up voltage: 0.7V (Typ.)
• High efficiency: 2.7V ≤ VOUT ≤ 5.0V upper 90 (Typ.)
• High output voltage accuracy: ±2.5
• Output voltage: 2.7V, 3.0V, 3.3V, 3.7V, 5.0V
• Output current up to 200mA
• Ultra low supply current IDD: 5μA (Typ.)
• Low ripple and low noise
• Low shutdown current: 0.1μA (Typ.)
• TO92, SOT89, SOT23 and SOT23-5 package
Applications
• Palmtops/PDAs
• Portable communicators/Smartphones
