Hw-133-v1.0 Datasheet -

: While rated for 3A, the module can get hot. If drawing more than 2A continuously, it is recommended to add a small heatsink or provide active cooling.

: It operates at a switching frequency of 150 kHz , allowing for smaller filter components and an efficiency rate generally between 80% and 92% depending on the voltage differential. Common Use Cases Hw-133-v1.0 Datasheet

: Draws less than 1mA when idle, making it ideal for battery-powered projects like the Raspberry Pi Zero. Low Ripple : While rated for 3A, the module can get hot
