产品概述
The TPS53129 is a dual, adaptive on-time D-CAP2™ mode synchronous buck controller. The TPS53129 enables
system designers to complete the suite of various end equipment’s power bus regulators with cost
effective, low component count, and low standby current solution. The main control loop for the
TPS53129 uses the D-CAP2™ mode control which
provides a very fast transient response with no external components.
The TPS53129 also has a
circuit that enables the device to adapt to both low equivalent series resistance (ESR) output
capacitors such as POSCAP or SP-CAP, and ultra-low ESR, ceramic capacitors. The fixed frequency
emulated adaptive on-time control supports seamless operation between PWM mode at heavy load
condition and reduced frequency operation at light load for high efficiency down to milliampere
range.The device provides convenient and efficient operation with input voltages from 4.5 V to 24 V
and output voltages from 0.76 V to 5.5 V.The TPS53129 is available in 4-mm × 4-mm 24-pin QFN (RGE) or 24-pin TSSOP (PW) packages,
and is specified from –40°C to 85°C ambient temperature range.
