• Manufacturer Part Number: sc1109acstrt
• Description: Sc1109 Synchronous Pwm Controller With Dual Low-dropout Regulator Controllers
• Manufacturer: Semtech Corporation

Unless specified: VOSENSE = V
Notes:
(1) All electrical characteristics are for the application circuit on page 16.
(2) Soft start function is performed after Vcc is above the UVLO and SS/EN is above 600mV. The Soft start
capacitor is then charged at a 10uA constant current until SS/EN is charged to above 1V.
(3) Guaranteed by design
(4) Tracking Difference is defined as the delta between 3.3V Vin and the LDO1, LDO2 output voltages during
the linear ramp up until regulation is achieved. The tracking voltage difference might vary depending on
MOSFETs RdS
(5) This device is ESD sensitive. Use of standard ESD handling precautions is required.
