Techcode TD1729
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.| Part No. | TD1729 |

GENERAL DESCRIPTION
FEATURES
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. The Power-OnReset function monitors the voltage on VCC to prevent wrong operation during power-on. The TD1729 has a 1ms digital soft-start and built-in an integrated output discharge method for soft-stop. An internal integrated soft-start ramps up the output voltage with programmable slew rate to reduce the start-up current. A soft-stop function actively discharges the output capacitors with controlled reverse inductor current. The TD1729 is available in 10pin TDFN 3x3 package.●
