7 / 19 page  uP9511R 7 uP9511R-DS-F0000, Oct. 2017 www.upi-semi.com () IMON SUM DC Hys OUT BOT TOP Hys PROGx R R N R I R R uA V × ⎟⎟ ⎟ ⎟ ⎠ ⎞ ⎜⎜ ⎜ ⎜ ⎝ ⎛ × = × = _ _ || 10 Where R TOP is the resistor connects from 5VCC to PROGX pin, and R BOT is the resistor connects from PROGX pin to GND. If V IMON < VPROG1, uP9511R operates in single phase; if VPROG1 < V IMON < VPROG2, uP9511R operates in dual phase; if VPROG2 < V IMON < VPROG3, uP9511R operates in four phase; if VPROG3 < V IMON < VPROG4, uP9511R operates in six phase; if VIMON > V PROG4, uP9511R operates in 8 phase. The uP9511R always keeps all-of-phase interleaved operation. When setting PROG1, PROG2, PROG3 and PROG4, always keep V PROG1 <VPROG2<VPROG3<VPROG4. Violating this rule may lead to unknown status and should be avoided. Short the PROG1, PROG2, PROG3 and PROG4 to GND to disable the auto-phase mode. Cold Boot and Warm Boot The uP9511R features programmable operation phase number of Cold Boot Mode and Warm Boot Mode. When PSI=Low and uP9511R first boots up (first time of 5VCC and EN goes high), controller will enter to Cold Boot Mode. Except the first boot up, when PSI=Low state and controller power up by EN control, then uP9511R will enter to Warm Boot Mode. Connect LPC pin to 5VCC with a voltage divider (Figure 3) to set the operation phase number of Cold Boot Mode and Warm Boot Mode. Figure 4 shows all the power states of uP9511R under each combination of 5VCC/EN/ PSI/VID signal. Table 3 shows the recommended resistance of the voltage divider.
