TPS51125电路图:

The TPS51125 is a cost-effective, dual-synchronous
buck controller targeted for notebook system power
supply solutions. The device provides 5-V and 3.3-V
LDOs and requires few external components. The
270-kHz VCLK output can be used to drive an
external charge pump, thus generating gate drive
voltage for the load switches without reducing the
efficiency of the main converter. The TPS51125
supports high-efficiency, fast-transient response and
provides a combined power-good signal. Out-of-
Audio mode light-load operation enables low acoustic
noise at much higher efficiency than conventional
forced PWM operation. Adaptive on-time D-CAP™
control provides convenient and efficient operation.
The part operates with supply input voltages ranging
from 5.5 V to 28 V and supports output voltages from
2 V to 5.5 V. The TPS51125 is available in a 24-pin
QFN package and is specified from -40°C to 85°C
ambient temperature range.
