H6603 is an excellent step-down and constant-voltage power supply chip, which has the characteristics of few peripheral components, simple circuit, high efficiency and low heat generation.
The H6603 is a built-in power MOSFET step-down switching converter. Over a wide input range, its peak output current can reach 08A with excellent load and line regulation.
The current-controlled mode provides fast transient response and makes the loop easier to stabilize. Fault protection includes cycle-by-cycle current limiting and over-temperature protection.
In practical applications, it can provide stable voltage output for various electronic devices, and also has functions such as over-current protection, over-temperature protection and short-circuit protection, which can effectively protect the safety of the circuit and the chip itself.
The H6603 is available in an ESOP-8 package.
