DESCRIPTION
HM2742 is a high-efficiency and high-precision non-isolated step-down switch Power constant voltage control driver chip. Suitable for 85VAC~265VAC Non-isolated Buck topology with full range input voltage, especially suitable It is used to drive power supplies such as small household appliances and white goods. HM2742 integrates a 500V power switch inside, adopting a unique constant Voltage control mode, the system can work in inductor current discontinuous mode and Inductor current continuous mode. The scheme design is flexible, the peripheral application is simple, Can use lower system cost to make greater output power. HM2742 has multiple protection functions, including VBP clamp circuit, VBP under-voltage protection, output short-circuit protection, overheating protection and other functions, Strong reliability.
Features
