Result for 50% and 25% is rounded down Example: 15% IFCHG setting at 50% results in 7% output 2. Result minimum is always 1% Example: 2% IFCHG setting at 25% reduction is still 1% REG 0x1D: Temperature Setting (R/W) (NVM) Bit Name Description Comment 7 FREQ_SEL[1] 0 Frequency Selection Settings for SMPS Settings: 00: 125kHz 01: 250kHz 10: 500kHz 11: 1MHz Note: These can NOT be changed “on the fly” and each setting requires a different inductor value and capacitors and compensation components. CARE SHOULD BE TAKEN WHEN WRITING TO THIS REGISTER TO AVOID CHANGING THE FREQUENCY WHILE OPERATING 6 FREQ_SEL[0] 0 5 DIS_SHIP_RENTER 0 0: Enable re-enter ship mode 1: Disable ship mode re-enter If set to 0, writing to SHIPM_ENTER (Reg 0x00 Bit 5) will allow the device to re-enter ship mode. If set to 1, device will ignore the SHIPM_ENTER command. 4 OTG_HOT[1] 0 00: VTH55C at 55°C 01: VTH60C at 60°C 10: VTH65C at 65°C 11: Disable shutdown OTG mode or Disable JEITA Mode Hot Temperature Monitor TH / NTC Thresholds 3 OTG_HOT[0] 1 2 OTG_COLD 0 0: VTH0C at 0°C 1: VTH-10C at -10°C OTG mode or Disable JEITA Mode Cold Temperature Monitor TH / NTC Thresholds 1 TREG[1] 1 00: Disable 01: 80°C 10: 100°C 11: 120°C Die temperature regulation threshold 0 TREG[0] 1 |
