Product data sheet Rev. 1 — 26 May 2015 7 of 35 NXP Semiconductors SSL8516BT Greenchip PFC and flyback controller 7.1.2 Power-down mode The power-down mode can be activated for very low standby power applications by pulling the VVINSENSE < Vth(pd) level. The SSL8516BT stops switching and safe restart protection is activated. The high-voltage start-up current source is also disabled during power-down and the SSL8516BT does not restart until VVINSENSE is raised again. During Power-down mode, all internal circuitry is disabled except for a voltage detection circuit on the VINSENSE pin. This circuit is supplied by the HV pin and draws 12 A from the HV pin for biasing. The protection signal resembles an imaginary protection trigger. Fig 4.
