TPS5432
www.ti.com SLVSB89A – MARCH 2012 – REVISED OCTOBER 2012 2.95V to 6V Input, 3A Output, 700kHz Synchronous Step Down Converter
Check for Samples: TPS5432 FEATURES DESCRIPTION The TPS5432 is a 6V, 3A, low Iq, current mode,
synchronous monolithic buck converter with
integrated MOSFETs. The TPS5432 enables small
designs by integrating the MOSFETs, implementing
current mode control to reduce external component
count, reducing inductor size by 700kHz switching
frequency. SOIC-8 package with exposed thermal
pad provides both thermally enhanced solution and
easy to use. 1 2 Two 70mО© (typical) MOSFETs for 3A
