TD1729 - High-Performance PWM Controller

Features

  • The TD1729 is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The TD1729 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The TD1729 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the TD1729 provides very high efficiency over light to heavy loads with loading- modulated switching frequencies. In PWM Mode, the converter works.

Techcode® High-Performance PWM Controller DATASHEET TD1729 General Description Features The TD1729 is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The TD1729 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The TD1729 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the TD1729 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 TD1729 is equipped with accurate positive current- limit, output under-voltage, and output over-voltage protections, perfect for NB applications.
