6.6.74 (B1h) USER_DATA_01 (COMPENSATION_CONFIG)

CMD Address	B1h
Write Transaction:	Write Block
Read Transaction:	Read Block
Format:	Unsigned Binary (5 bytes)
Phased:	No
NVM Back-up:	EEPROM or Pin Detection
Updates:	Conversion Disable: on-the-fly. Conversion Enable: hardware update blocked. To update hardware after write while enabled, store to NVM with (15h) STORE_USER_ALL and (16h) RESTORE_USER_ALL or cycle AVIN below UVLO.

Configure the control loop compensation.

Table 6-91 Register Field Descriptions

Bit	Field	Access	Reset	Description
25:24,39:38	SEL_CZI[3:0]	RW	NVM	Selects the value of current loop integrating capacitor. CZI = 6.66 pF x CZI_MUL x 2^SEL_GMI[1:0] x SEL_CZI[3:0]
37:33	SEL_CPI[4:0]	RW	NVM	Selects the value of current loop filter capacitor. CPI = 3.2 pF x SEL_CPI[4:0]
32	SEL_CZI_MUL	RW	NVM	Selects the value of current loop integrating capacitor multiplier. 0b: CZI_MUL = 1 1b: CZI_MUL = 2
31:26	SEL_RVI[5:0]	RW	NVM	Selects the value of current loop mid-band gain resistor. RVI = 5 kΩ x SEL_RVI[5:0]
9:8, 23:22	SEL_CZV[3:0]	RW	NVM	Selects the value of voltage loop integrating capacitor. CZV = 125 pF x 2^SEL_GMV[1:0] x SEL_CZV[3:0]
21:17	SEL_CPV[4:0]	RW	NVM	Selects the value of voltage loop filter capacitor. CPV = 6.25 pF x SEL_CPV[4:0]
16	Reserved	RW	NVM	Reserved, set to 0b
15:10	SEL_RVV[5:0]	RW	NVM	Selects the value of voltage loop mid-band gain resistor. RVV = 5 kΩ x SEL_RVV[5:0]
7:6	Reserved	RW	NVM	Reserved, set to 00b
5:4	SEL_GMV[1:0]	RW	NVM	Selects the value of voltage error transconductance. GMV = 25 µS x 2^SEL_GMV[1:0]
3:2	Reserved	RW	NVM	Reserved, set to 00b
1:0	SEL_GMI[1:0]	RW	NVM	Selects the value of current error transconductance. GMI = 25 µS x 2^SEL_GMI[1:0]

(B1h) USER_DATA_01 (COMPENSATION_CONFIG) can be written to while output conversion is enabled, but updating those values to hardware will be blocked. To update the value used by the control loop:

Disable conversion, then write to (B1h) USER_DATA_01 (COMPENSATION_CONFIG).
Write to (B1h) USER_DATA_01 (COMPENSATION_CONFIG) while conversion is enabled, store PMBus values to NVM using (15h) STORE_USER_ALL, clear the (B1h) USER_DATA_01 (COMPENSATION_CONFIG) bit in (EEh) MFR_SPECIFIC_30 (PIN_DETECT_OVERRIDE), then cycle AVIN or use the (16h) RESTORE_USER_ALL command.

Due to the complexity of translating the 5-byte HEX value of (B1h) USER_DATA_01 (COMPENSATION_CONFIG) into analog compensation values, users are recommended to use the tools available on the TPS546B24S product folder such as the TPS546x24S Compensation and Pin-Strap Resistor Calculator design tool.
