Overview
MAX77231
EVALUATION KIT AVAILABLE
2.
75V to 4.
8V Input, 10mA Output, 35µVRMS Ultra-Low Noise Boost Regulator
General Description
The MAX77231 is optimized for boost applications, requiring very low ripple/noise and small PCB space.
Output ripple and noise are suppressed to 35µVRMS (in 1MHz BW) by a PMOS linear post-regulator set 0.
5V below the boost regulator output to reject noise while optimizing efficiency.
The boost regulator operates using a 1µH/400mA inductor and 2.
2µF (0.
22 (min) after derating) output capacitance.
Fast transient response and stable operation are guaranteed using a current-limited PFM architecture.
A PMOS low-noise linear post-regulator attenuates boost converter rip...
