Check for Samples: TPS54525 FEATURES DESCRIPTION The TPS54525 is an adaptive on-time D-CAP2в„ў
mode synchronous buck converter. The TPS54525
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
TPS54525 uses the D-CAP2в„ў mode control which
provides a very fast transient response with no
external compensation components. The TPS54525
also has a proprietary circuit that enables the device
to adopt to both low equivalent series resistance
(ESR) output capacitors, such as POSCAP or SPCAP, and ultra-low ESR ceramic capacitors. The
device operates from 4.5-V to 18-V VIN input. The
output voltage can be programmed between 0.76 V
and 5.5 V. The device also features an adjustable
soft start time and a power good function. The
TPS54525 is available in the 14-pin HTSSOP
package, and designed to operate from –40°C to
85В°C. 1 23 D-CAP2в„ў Mode Enables Fast Transient
