描述
Spread spectrum may be enabled through SMBus programming. Spread spectrum typically reduces system EMI by 8dB to 10dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The 952302 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
