Datasheet Specifications

Part number: AAT2749
Manufacturer: Skyworks
File Size: 0.99 MB
Datasheet: AAT2749-Skyworks.pdf
Description: 3.0MHz Step-Down Converter and Low-V LDO

Features

*  VIN Range: 2.3V to 5.5V
*  Two Outputs ▪ VOUT_BUCK = 1.8V ▪ VOUT_LDO = 1.0V, 1.2V
*  Step-Down Converter ▪ Ultra-Small 0603 Inductor (Height 1mm) ▪ Up to 92% Efficiency ▪ 3.0MHz Switching Frequency ▪ MODE Selection Pin to Select Forced PWM or PWM/ LL Operation Mode ▪ Curre

Applications

* Fixed frequency, low noise operation can be forced by a logic signal on the MODE pin. The AAT2749 also contains a 300mA LDO regulator with input voltage capability as low as 1.62V. The LDO regulator power input can be tied directly to the output of the step-down regulator to increase efficiency. To
