IPC: H02M1/00
Filed: 1998-12-30
Abstract: PURPOSE: A control circuit is provided to supply the power automatically to a mobile terminal when a battery is connected. CONSTITUTION: A power supply control circuit(20) connected between a battery(21) and a DC-DC transformer(23) automatically drives the DC-DC transformer by using a pulse generated by the load when a battery is connected to a mobile terminal. A power supply circuit comprises two capacitors, three diodes, three registers, and a transistor. When a pulse is generated, the charged capacitor 1(C1) turns on the diode 1(D1) and the base of transistor becomes to the high level. It follows that the collector is connected through register 1(R1) to the low level and the control pin of the DC-DC transformer becomes to the low level. Thus the power is supplied to the mobile terminal while the control pin is at the low level.
