TPS62913: TPS62913 Regulator in place of TPS7A85 LDO and TPS546A24A buck regulator

Part Number: TPS62913
Other Parts Discussed in Thread: TPS7A85, TPS546A24A,

Hello Everyone,

I want to use TPS62913 in place of LDO (TPS7A85) and TPS546A24A for current consumption up to 2.5A.

My requirement is

1. Replacement of TPS7A85 (3.3V@1.2/1.5A)-

a. Vin (4.75V, 5V, 5.25V)/ (11.4V, 12V, 12.6V)

b. Input Ripple= 50mV/ 120mV

c. Vout ripple = 3mV and Tolerance= 1% (33mV)

d. Fsw= 1MHz

2. Replacement of TPS546A24A: Vin= (11.4V, 12V, 12.6V), Vin_ripple= 120mV

A. Vout and Iout= 0.88V/ 1.8V/ 3.3V@2.5A/2.5A/1.5A, Vout ripple= 3-10mV, Voltage Tolerance= 1%

Can someone suggest and clarify for selection, design and requirements?

Your quick response in this regard will be highly appreciable.
