Operation notes
(1) The output current should be reduced according to an increase in the input voltage or ambient
temperature. Use the module within the derating curve range.
(2) In case that the output is controlled by switching on and off utilizing pin 7 or in case that the input voltage
is applied, a large inrush electrical current may flow. Be minded to use within the allowable operating range.
This allowable operating range is specified by the safety operating range of the switching transistor in the
module. The amount of the inrush current varies depending on the output impedance of the input power
supply or the capacity value of the capacitor to be connected to the output.
(3) Protection circuit for output current is incorporated. In case that the output is short-circuited, the output will be
latched by switching off. The protection circuit can be cancelled by making CTL terminal active state (CTL=
HIGH), after once making it standby state (CTL=LOW), or by resupplying the power. However, in case that the
protection circuit is cancelled by resupplying the power source, it may not be cancelled even by resupplying
the power source in the state that the electrical charge is remained in CIN (the state that voltage is remained
in VIN) even after the power source is switched off.
(4) The rising time of the input voltage should be made within 5ms. There may be a case that the protection
circuit is activated.
(5) I / O smoothing capacitors should be connected between I / O and GND terminals.
(6) Normally, use by short-circuiting pins 1, 2, 3, pins 4, 5, 6, and pins 9, 10, 11 (BP5232A25) respectively.
(7) A large ripple current flows to the input smoothing capacitor due to the output load. Be minded to use
within the allowable ripple current of the capacitor.
(8) The capacitor with a particularly low impedance is used as the output smoothing capacitor C2 so as to
suppress the output ripple voltage. Select the capacitor according to the purpose of use in each case.
