Hw-133-v1.0 Datasheet | ^new^

While the internal chip is the STMicroelectronics L298N (a legacy dual H-bridge), the HW-133 refers to the module design—specifically the v1.0 PCB layout that integrates the chip with heat sinks, 5V regulation, and convenient screw terminals.

is an ultra-compact, high-efficiency designed for applications requiring precise voltage conversion in tight spatial constraints. Built around the high-performance Monolithic Power Systems (MPS) MP1584EN switching regulator chip, this module functions as an adjustable, non-isolated synchronous buck converter. It efficiently steps down higher DC input voltages ranging from 4.5V to 28V to a stable, lower user-defined output voltage. ⚙️ Core Technical Specifications

Precision Adjustment Hw-133-v1.0 Datasheet

The HW-133-V1.0 is a highly integrated system-on-chip (SoC) designed for various applications, including industrial control, medical devices, and consumer electronics. To effectively utilize this powerful component, it's essential to understand its datasheet, which provides critical information on its specifications, features, and operating conditions.

Adhering a small aluminum miniature heatsink directly onto the MP1584EN chip is mandatory to prevent thermal shutdown protections from kicking in. Noise Suppression in Sensitive Environments While the internal chip is the STMicroelectronics L298N

Traditional linear regulators (like the LM7805) burn off excess voltage directly as waste heat. For example, dropping 12V down to 5V at 1A forces a linear regulator to dissipate 7 Watts of heat, requiring massive heatsinks. The HW-133-V1.0 uses pulse-width modulation (PWM) fast-switching cycles to step down voltage. Under the same conditions, it operates at roughly 90% efficiency, wasting less than 0.6 Watts of power.
