High-Performance PWM Controller
DATASHEET
TD1730
General Description
Features
The TD1730 is a single‐phase, constant‐on‐time, z
synchronous PWM controller, which drives N‐channel z
MOSFETs. The TD1730 steps down high voltage to z
generate low‐voltage chipset or RAM supplies in notebook z
computers.
The TD1730 provides excellent transient response and z
accurate DC voltage output in either PFM or PWM Mode. In z
Pulse Frequency Mode (PFM), the TD1730 provides very high z
efficiency over light to heavy loads with loading‐ modulated z
switching frequencies. In PWM Mode, the converter works z
nearly at constant frequency for low‐noise requirements.
