The TPS54326 is an adaptive on-time D-CAP2?
mode synchronous buck converter. The TPS54326
enables system designers to complete the suite of
various end equipment’s power bus regulators with a
cost effective, low component count, low standby
current solution. The main control loop for the
TPS54326 uses the D-CAP2? mode control which
provides a fast transient response with no external
components. The adoptive on-time control supports
seamless operation between PWM mode at heavy
load condition and reduced frequency Eco-mode?
operation at light load for high efficiency.
The TPS54326 also has a proprietary 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 device operates from 4.5-V to 18-V
V CC input , and from 2-V to 18-V VIN input power
supply voltage. The output voltage can be
programmed between 0.76 V and 5.5 V. The device
also features an adjustable slow start time and a
power good function. The TPS54326 is available in
the 14 pin HTSSOP or 16 pin QFN package, and
designed to operate from –40°C to 85°C.
