Part Number:TPS92515
Hello there
I have to design a standby power consumption optimized design with the TPS92515.
The LEDs are turned off: Vadj is directly tied to Vcc. PWM input is controlled by uC and has a logic level of 0.
So everything is switched off.
My measurements show a power consumption of 4.9mA @24VDC and I can measure a leakage voltage at pin sw= 0.069V
From the datasheet 7.5 -> Electrical characteristics -> System currents
Icq operating current not switching VIADJ=VCC 0.85mA (typ) / 1.5mA (max)
How I can reach a 1.5mA operating current? Do I misunderstand operating current?
Thanks and regards,
Christian
