DescriptionThe FAN5232 is a high efficiency and high precision DC/DC
controller for PCs. It has a synchronous switcher whose
output can be adjusted from 5V up to 80% of Vin. It also has
two linear regulators for standby, 3.3V and 5V . The PWM
utilizes both input and output voltage feedback in a
current-mode control, allowing for fast and stable loop
response over a wide range of input and output variations.
Synchronous switching provides best efficiency over a wide
range of loads. Current sense based on MOSFET R
DS,on
gives maximum efficiency, while also permitting use of an
optional sense resistor for high precision.
The FAN5232 is available in a 14 pin TSSOP package.
