2A PWM Step-Down Converter in 2mm x 2mm WLP/UCSP for PA Power
General Description
The MAX8836Z high-frequency step-down converter is optimized to provide a fixed output
voltage with ultralow dropout.
The device integrates a high-efficiency PWM step-down converter for medium- and low-power transmission, and a 60mΩ typical bypass FET for ultra low-dropout operation.
A 200mA low-noise, high-PSRR low-dropout regulator (LDO) is also integrated.
Fast-switching allows the use of small ceramic input and output
capacitors while maintaining low ripple
voltage.
The feedback network is integrated, further reducing external component count and total solution s...
