1.3 Description  
The TPS657120 provides three configurable step-down converters with up to 2 A output current. It also  
contains 2 LDO regulators. LDO1 can be supplied from either the input voltage directly or from a pre-  
regulated supply such as DCDC1 or DCDC2. The input voltage to LDO2 is used as an analog supply input  
and therefore needs to be tied to the input voltage at the same voltage level with VINDCDC1/2 and  
VINDCDC3. The internal power-up/power-down controller is configurable and can support any power-  
up/power-down sequences (OTP based). All LDOs and DCDC converters are controllable by a MIPI RFFE  
compatible interface and / or by pins PWRON, CLK_REQ1 and CLK_REQ2. In addition, there is a  
nRESET as well as a RFFE address select (ADR_SELECT) input which can alternatively be used as  
general purpose I/Os with a 1mA sink capability. The TPS657120 comes in a 6 ball x 5 ball WCSP  
package (2.5mm x 2.3mm) with a 0.4mm pitch. To request a full data sheet, please send an email to:
