MP174GJ-Z Description

Short technical summary and product information.

The MP174GJ-Z from Monolithic Power Systems is a primary-side constant voltage (CV) regulator designed for off-line low-power applications. It supports Buck, Buck-Boost, Boost, and Flyback topologies, simplifying circuit design by eliminating the need for an opto-coupler. This regulator integrates a 700V MOSFET and a current source, enabling efficient operation with up to 5W output power.

 

Key features include a low no-load power consumption of less than 30mW and green-mode operation where peak current and switching frequency decrease with load, improving light-load efficiency. The device incorporates comprehensive protection features such as thermal shutdown (OTP), VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), and open loop protection.

 

The MP174GJ-Z is supplied in a compact TSOT-23-5 package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). This component is ideal for applications like home appliances, white goods, consumer electronics, industrial controls, and standby power supplies.
