Supplementary explanation of test circuit
No. 41 Measure SW pin oscillation frequency upon VSYS1=0V and VSTART=0V.
No. 42 Measure SW pin oscillation frequency upon VSYS1=3.2V.
No. 43 Measure SW pin oscillation frequency when pulse wave of 88.2kHz has been inputted to CLK pin.
No. 44 Measure minimum pulse width outputted to SW pin upon increasing E0 pin voltage from 0.5V.

No. 45 Measure SW pin pulse duty upon VSYS1=0V and VSTART=0V.
No. 46 Measure SW pin pulse duty upon VSYS1=3.2V and CLK=0V.
No. 47 Measure SW pin pulse duty upon VSYS1=3.2V and CLK=88.2kHz.
No. 55 &56 Check the synchronization of SW pin when low level of pulse wave inputted to CLK pin has been
0.8V and high level has been 2.0V.
No. 61 &63 BSEN pin voltage when EMP pin varies from “H”to “L”upon decreasing the BSEN pin voltage
(VSEL=0V).
The voltage width until EMP pin varies “L”to “H”upon increasing BSEN pin voltage from that voltage shall be
hysteresis width.
No. 62 &64 BSEN pin voltage when EMP pin varies from “H”to “L”upon decreasing the BSEN pin voltage
