General Description
Features
The TD9000 is a single‐phase, constant‐on‐time, synchron‐
ous PWM controller, which drives N‐channel
MOSFETs.
The TD9000 steps down high
voltage to generate low
voltage chipset or RAM supplies in notebook computers.
The TD9000 provides excellent transient response and
accurate DC
voltage output in either PFM or PWM Mode. In
Pulse Frequency Mode (PFM), the TD9000 provides very high
efficiency over light to heavy loads with loading‐ modulated
switching frequencies. In PWM Mode, the converter works
nearly at constant frequency for low‐noise requirements.
The TD9000 is equipped with accurate positive current‐ limit,
output under‐
voltage, and output over‐
voltage pr...
