TPS54326

The TPS54326 is an adaptive on-time D-CAP2 mode synchronous buck converter. The TPS54325 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.

Features of the TPS54326 are:(1)D-CAP2 mode enables fast transient response;(2)low output ripple and allows ceramic output capacitor;(3)wide VCC input voltage range: 4.5 V to 18 V;(4)wide VIN input voltage range: 2.0 V to 18 V;(5)output voltage range: 0.76 V to 5.5 V;(6)highly efficient integrated FET's optimized for lower duty cycle applications;(7)high efficiency, less than 10 mA at shutdown;(8)high initial bandgap reference accuracy;(9)adjustable soft start;(10)Pre-biased soft start;(11)700-kHz switching frequency (fSW);(12)cycle by cycle over current limit;(13)power good output.
