MAX1920EUT+T

The MAX1920EUT+T is a low voltage, 400mA step-down DC-DC converter in 6 pin SOT-23 package. This step-down converter delivers over 400mA to outputs as low as 1.25V. It use a unique proprietary current-limited control scheme that achieves over 90% efficiency. Device maintain extremely low quiescent supply current and its high 1.2MHz (max) operating frequency permits small low cost external components. Internal synchronous rectification greatly improves efficiency and eliminates the external Schottky diode required in conventional step-down converter. It also include internal digital soft start to limit input current upon start-up and reduce input capacitor requirements. It is used in next-generation wireless handsets, PDAs, palmtops and handy-terminals and CDMA power amplifier supply.

• Input voltage range from 2.5V to 5.5V
• Operating temperature range from 40°C to +85°C
• Quiescent supply current is 50µA
• Logic controlled shutdown is 0.1µA
• Adjustable output voltage
• Initial accuracy of ±1.5%
• Output voltage range from 1.25V to 4V at IN = 4.5V
