TD1729 High-PerformancePWM Controller
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 RAMsupplies in notebook computers.
The TD1729 provides excellent transient response andaccurate DC voltage output in either PFM orPWM Mode.In Pulse Frequency Mode (PFM),the TD1729 provides very high efficiency over light toheavy loads with loading- modulated switching frequencies. In PWM Mode, the converter worksnearly 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. The Power-On- Reset function monitors the voltageon VCC to prevent wrong operation during power-on. The TD1729 has a 1ms digital soft-start andbuilt-in an integrated outputdischarge method for soft-stop. An internal integrated soft-start rampsup the output voltage with programmable slew rate to reduce the start-up current. A soft-stop functionactively discharges the output capacitors with controlled reverse inductor current.

The TD1729 is available in 10pin TDFN 3x3 package.
