D-CAP2
Mode Enables Fast Transient
Response
The TPS54429 is an adaptive on-time D-CAP2
mode synchronous buck converter. The TPS54429
Low Output Ripple and Allows Ceramic Output
enables system designers to complete the suite of

’s power bus regulators with a
Wide VIN Input Voltage Range: 7 V to 18 V
cost effective, low component count, low standby
Output Voltage Range: 0.76 V to 5.5 V
current solution. The main control loop for the
TPS54429 uses the D-CAP2
mode control which
