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.
The TPS5432 provides accurate regulation for a variety of loads with an accurate 3.0%
voltage reference over temperature.
Efficiency is maximized through the integrated 70mΩ MOSFETs and 360μA typical supply
current. Using the enable pin, shutdown supply current is reduced to 2 µA by entering a shutdown
The output voltage startup ramp is controlled by the slow start pin. A ceramic capacitor
at this pin can easily adjust the slow start time.
Frequency fold back and thermal shutdown protects the device during an over-current
