AN_201702_PL52_01415 W 5 V charger reference design with 700 VCoolMOS™ P7EVAL_15W_5V_FLYB_P7 using IPS70R1K4P7S, ICE2QS03G, BSC067N06LS3 GThis document introduces a 15 Whigh efficiency USB charger reference design with a 5 V output voltage using the QR PWM IC ICE2QS03G with CoolMOSTM IPS70R1K4P7S (IPAK SL) and a secondary side synchronous rectification IC with OptiMOSTM BSC067N06LS3 G (SuperSO8) in a small formfactor, high efficiency and variousprotections for a highly reliable system.

Merkmale

  • 500V startup cell for IC self power supply during various states,• digital frequency reduction with decreasing load for higher efficiency• active burst mode operation for ultra-low standby power (<1W @ 0.5W load)• cycle by cylce peak current limitation, maximum output power limitation with input voltage compensation• extensive protection features to protect the IC and the system from various fault conditions e.g. output OVP latch, VCC OVP/UVP, OLP, Output OVP, Short-winding, etc.
