JAJSFC9B September 2017 – June 2018 TPS560430
UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
For FPWM version, TPS560430 is locked in PWM mode at full load range. This operation is maintained, even in no-load condition, by allowing the inductor current to reverse its normal direction. This mode trades off reduced light load efficiency for low output voltage ripple, tight output voltage regulation, and constant switching frequency.
