General Description
The MAX8836Z high-frequency step-down converter is
optimized to provide a fixed output voltage with ultra-
low dropout. The device integrates a high-efficiency
PWM step-down converter for medium- and low-power
transmission, and a 60m&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 size.At high
duty cycle, the MAX8836Z automatically switches to the
bypass mode, connecting the input to the output
through a low-impedance (60m& typ) MOSFET. The
LDO in the MAX8836Z is designed for low-noise opera-
tion (35礦
RMS
typ). Both the PWM step-down and LDO
are individually enabled through separate logic-control
interfaces.
The MAX8836Z is available in 16-bump, 2mm x 2mm
WLP and UCSP" packages (0.7mm max height).
