Mingjiada Supply TI TPSM82902 2A High Efficiency, Low IQ Synchronous Buck Converter Module With Integrated Inductor

In portable electronics, industrial sensors, communication modules and Internet of Things (IoT) devices, power supply design is facing the triple challenge of ‘compact size, high efficiency and low standby power consumption’. Shenzhen Mingjiada Electronics Co., Ltd. — a long-standing supplier of the TPSM82902 synchronous buck converter module from Texas Instruments (TI) — offers a plug-and-play power solution for space-constrained and power-sensitive applications, featuring a 2A output capability, an integrated inductor and low quiescent current.

TPSM82902 is a 2A, high-efficiency, low-IQ synchronous buck converter module (Power Module) launched by TI. It employs a modular design with an integrated inductor and power devices, integrating the controller, MOSFET, inductor and compensation network within a single package, thereby significantly simplifying peripheral circuit design and shortening the development cycle. The device supports a wide input voltage range and adjustable output voltage, and features low quiescent current (IQ), maintaining high conversion efficiency under light load and in standby modes, making it particularly suitable for battery-powered and ‘always-on’ applications.

Detailed Key Features of the TPSM82902:
High efficiency across a wide range of duty cycles and loads
IQ: 4 µA (typical)
62 mΩ high-side and 22 mΩ low-side RDS(ON)
3 mm × 2.8 mm × 1.6 mm MicroSiP™ package
Continuous output current up to 2 A
Feedback voltage accuracy of ±0.9% across the entire temperature range (-40 °C to 125 °C)
Configurable output voltage options:
VFB external divider: 0.6V to 5.5V
VSET internal divider: 16 voltage options (0.4V to 5.5V)
DCS-Control topology with 100% mode
Flexibility via the MODE/S-CONF pin
2.5MHz or 1.0MHz switching frequency
Forced PWM or automatic (PFM) power-saving mode with dynamic mode-switching option
Automatic Efficiency Enhancement (AEE)
Output discharge on/off

With its 2A output, low IQ and modular integration advantages, the TPSM82902 is widely used in:
Data centres and enterprise computing
Wired networks
Wireless infrastructure
Factory automation and control
Test and measurement
