ZHCSTR3B December 2010 – November 2023 TPS53315
PRODUCTION DATA
The TPS53315 adds a ramp signal to the 0.6-V reference to improve jitter performance. The feedback voltage is compared with the reference information to keep the output voltage in regulation. By adding a small ramp signal to the reference, the signal-to-noise ratio at the onset of a new switching cycle is improved. Therefore the operation becomes less jittery and more stable. The ramp signal is controlled to start with –7 mV at the beginning of an on-cycle and becomes 0 mV at the end of an off-cycle in steady state.
