IPC: H01L21/822
Filed: 1982-12-18
Abstract: PURPOSE:To operate an IC in the prescribed performance by the external voltage in a wide range by generating a low constant voltage lower than an internal power source line to detect the output in the prescribed threshold value, and applying the detected output to the control terminal of a transistor to lower the power source voltage. CONSTITUTION:An enhancement type P-channel FET101 is employed for a step- down circuit 32, the source is connected to an external power source terminal 10(VCC), the drain is connected to an internal power source line 40(VINT), and the gate is connected to a control terminal. If VINT<VTH+DELTAV, where the threshold voltage of a voltage detector 34 is represented by VTH and the constant voltage drop of a constant-voltage circuit 33 is represented by DELTAV, the detector 34 in which C-MOS inverters 303, 304 are connected in cascade becomes a low level VSS, the conductivity of the FET101 increases to cause the VINT to rise. If VINT>VTH+V, the detector 34 becomes a high level VCC, the conductivity of the FET decreases, the VINT drops, and VINT=VTH+DELTAV is set. Even if the externally supplied voltage varies in a wide range, the VINT can be maintained at the prescribed value by selecting the VTH, DELTAV, and an IC which includes ultrafine channel length can be stably operated.

Abstract: PURPOSE:To drive a switching transistor(TR) in an on-time ratio over a wide range by modulating a pulse signal with a frequency sufficiently higher than a signal frequency by a pulse width control signal and passing this signal through a pulse transformer. CONSTITUTION:A PWM control circuit 1 compares a control signal (a) with a reference voltage (b) and outputs a pulse width modulation signal (c) of a frequency f1 having a pulse width Tp in response to a difference voltage.

The signals (d), d' are fed to AND circuits 4, 5, in which they are ANDed with a pulse width modulation signal (c). Since a pulse transformer 9 is designed to be operated at the frequency f2, for example, let f1 be 10kHz and f2 be 1kHz, then the switching TR is driven in an on-time ratio of 1-100% with respect to a conventional on-time ratio of 10-50%.
