Aimtron Technology AT1366B
The AT1366B provides complete control for a DC/DC converter optimized for high-performance microprocessor applications. It is operated on current mode architecture for excellent line and load transient response. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode.FEATURES
● High efficiency (95%) possible● No Schottky Diode Required
● 800mA Output Current at 5V input 3.3V output
● Oscillation frequency 1.0MHz
● Built-in ON/OFF Function
● Built-in Short Circuit Protection
● Low Dropout Operation: 100% Duty Cycle
● Stand-by current max. 1µA
● Input voltage: 2.5V ~5.5V
APPLICATIONS
● Power Supply for portable devicesGENERAL DESCRIPTION
1MHz operation frequency is allowing the use of small surface mount inductor and capacitor. The AT1366 is a family of low-noise synchronous step-down DC/DC converters that is ideally suited for systems powered from a 1-cell Li-ion battery or from a 3-cell to 4-cell NiCd, NiMH, or alkaline battery. It can also be used to USB-Based power system.
