D-CAP2 Mode Enables Fast Transient
Response
The TPS54327 is an adaptive on-time D-CAP2
mode synchronous buck converter. TheTPS54327
Low Output Ripple and Allows Ceramic Output
enables system designers to complete the suite of
Capacitor
various end equipment’s power bus regulators with a
Wide VIN Input Voltage Range: 4.5 V to 18 V
cost effective, low component count, low standby
Output Voltage Range: 0.76 V to 7.0 V
current solution. The main control loop for the
TPS54327 uses the D-CAP2 mode control which
Highly Efficient Integrated FET’s Optimized
provides a fast transient response with no external
for Lower Duty Cycle Applications
compensation components. The TPS54327 also has
– 100 m
(High Side) and 70 m (Low Side)
a proprietary circuit that enables the device to adopt
High Efficiency, less than 10 mA at shutdown
to both low equivalent series resistance (ESR) output
High Initial Bandgap Reference Accuracy
capacitors, such as POSCAP or SP-CAP, and
ultra-low
ESR
ceramic
capacitors.
The
device
Adjustable Soft Start
operates from 4.5-V to 18-V VIN input. The output
Pre-Biased Soft Start
voltage can be programmed between 0.76 V and 7 V.
700-kHz Switching Frequency (fSW)
The device also features an adjustable soft start time.
The TPS54327 is available in the 8-pin DDA
Cycle By Cycle Over Current Limit
package, and designed to operate from –40°C to
85°C.
