HTC KOREA TJ1509A
The TJ1509A series are monolithic IC designed for a step-down DC/DC converter, and own the ability of driving a 2A load without additional transistor component. The external shutdown function can be controlled by logic level and then come into standby mode. The internal compensation makes feedback control have good line and load regulation without external design.| Part No. | TJ1509A |
