PRODUCTION DATA
The design goals are VIN = 1.8 V, VOUT = 1.5 V, and IOUT = 1 A (maximum). The design optimizes transient response and meets a 1-ms start-up time with a start-up dominated by the soft-start feature. The input supply comes from a supply on the same circuit board. The available system rails for VBIAS are 2.7 V, 3.3 V, and 5 V.
The design space consists of CIN, COUT, CBIAS, CSS, VBIAS, R1, R2, and R3, and the circuit is from Figure 7-4.
This example uses a VIN of 1.8 V, with a VBIAS of 2.5 V.
