General Description
The TD1730 is a single‐phase,
constant‐on‐time,
synchronous PWM controller, which drives N‐channel
MOSFETs. The TD1730 steps down high voltage to
generate low‐voltage chipset or RAM supplies in notebook
computers.
The TD1730 provides excellent transient response and
accurate DC voltage output in either PFM or PWM Mode. In
Pulse Frequency Mode (PFM), the TD1730 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 TD1730 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 voltage on VCC to prevent
wrong operation during power‐on. The TD1730 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 TD1730 is available in 10pin TDFN 3x3 package.
