Hw-133-v1.0 Datasheet [portable]

Connect the power source only to the IN+ and GND terminals.

: Driving high-power LEDs that require consistent voltage and current.

Compared to traditional linear regulators (like the 7805), this module wastes very little energy as heat, which is critical for battery-operated devices.

The HW-133 adapters serve as specialized interfaces between programming hardware (such as the HW-130 programmer) and target CPLD devices. They convert standard programmer signals into device-specific programming protocols, ensuring reliable and efficient programming operations.

The module features a simple four-pad layout for easy integration: : Positive Input Voltage (4.5V - 28V) IN- : Input Ground/Negative OUT+ : Regulated Positive Output OUT- : Output Ground/Negative Common Applications

: The board gets noticeably warm; passive airflow or open-air mounting is advised. Connect the power source only to the IN+ and GND terminals

: Stepping down variable PV array voltages to charge battery banks or power microcontrollers.

Set a digital multimeter to DC Voltage mode and hold its probes against the and OUT- pads.

High-frequency multilayer ceramic capacitors placed across both input and output rails. These suppress voltage ripples and protect downstream devices from harmonic noise. Thermal Management Guidelines While the module is rated for a peak current of void setup() Serial

4.5V to 28V (some variants specify 4.75V to 23V).

Operates at a frequency (typically >340kHz) that avoids audible noise and maintains low output ripple (≤45mVpp). Cons:

Measure the voltage across OUT+ and OUT- using a digital multimeter.

The small size, high efficiency, and wide input/output range of the HW-133-v1.0 make it ideal for numerous applications, including:

Adjustable from 0.8V to 20V via an onboard potentiometer.
