Title:
VOLTAGE STABILIZING CIRCUIT AND POWER SUPPLY CIRCUIT AND REMOTE CONTROL HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2018/192081
Kind Code:
A1
Abstract:
Provided are a voltage stabilizing circuit (100) and a power supply circuit and a remote control having the voltage stabilizing circuit (100). The voltage stabilizing circuit (100) comprises a controller (1); at least two transistors (Q1, Q2); and current equalization resistors (R1, R2) correspondingly connected in series with emitter electrodes of the respective transistors (Q1, Q2). The at least two transistors (Q1, Q2) are connected in parallel. For the at least two transistors (Q1, Q2) connected in parallel, base electrodes thereof are connected to a control end of the controller (1), and the emitter electrodes thereof are connected to an input power supply (Vcc). Moreover, collectors of the at least two transistors (Q1, Q2) connected in parallel are connected to a back-end hardware module (3). The power supply circuit can realize current equalization of the transistors (Q1, Q2) and output a stabilized voltage.
