  • LMG5200EVM-02: low efficiency at low Iout and current pulses even without input signal

    Resolved
    Part Number: LMG5200EVM-02 Hello Team, I have 2 questions: 1) Can the efficiency be at 45% for these conditions: Vin = 48V; Vout = 5V; Iout = 0.5A; Fsw = 2.5MHz ? Measured input power 5.5W output power: 0.5A x 5V = 2.5W So power losses of 3W are bigger…
