TPS54626
www.ti.com SLVSC34 – AUGUST 2013 4.5V to 18V Input, 6.5-A Synchronous Step-Down SWIFT™ Converter with ECO-Mode™
Check for Samples: TPS54626 FEATURES DESCRIPTION The TPS54626 is an adaptive on-time D-CAP2в„ў
mode synchronous Buck converter. The TPS54626
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
TPS54626 uses the D-CAP2в„ў mode control which
provides a very 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
operation at light load for high efficiency. The
TPS54626 also has a proprietary circuit that enables
the device to adopt to both low equivalent series
resistance (ESR) output capacitors, such as SP-CAP
and ultra-low ESR ceramic capacitors. The device
operates from 4.5-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 soft start time and a power good
function. The TPS54626 is available in the 14 pin …
