TPS54328

The TPS54328 is an adaptive on-time D-CAP2 mode synchronous buck converter. The TPS54328 enables system designers to complete the suite of various end-equipment power bus regulators with a cost effective, low component count, low standby current solution.

Features of the TPS54328 are:(1)D-CAP2 mode enables fast transient response;(2)low output ripple and allows ceramic output capacitor;(3)wide VIN input voltage range: 4.5 V to 18 V;(4)output voltage range: 0.76 V to 7.0 V;(5)highly efficient integrated FETs optimized for lower duty cycle applications;(6)high efficiency, less than 10 mA at shutdown;(7)high initial bandgap reference accuracy;(8)adjustable soft start;(9)pre-biased soft start;(10)700-kHz switching frequency (fSW);(11)cycle by cycle over current limit;(12)auto-skip eco-mode for high efficiency at light load.

The absolute maximum ratings of the TPS54328 can be summarized as:(1):the parameter is input voltage range,the value is -0.3 to 20,the unit is V;(2):the parameter is output voltage range,the value is -0.3 to 6.5,the unit is V;(3):the parameter is voltage from GND to thermal pad, Vdiff,the value is -0.2 to 0.2,the unit is V;(4):the parameter is electrostatic dischargeb human body model (HBM),the value is 2,the unit is kV;(5):the parameter is electrostatic dischargeb charged device model (CDM),the value is 500,the unit is V;(6):the parameter is operating junction temperature, TJ,the value is -40 to 150,the unit is ;(7):the parameter is storage temperature, Tstg,the value is -55 to 150,the unit is .
