Mingjiada Supply/Recycle TI TPSM82902SISR 2A High Efficiency, Low IQ Synchronous Buck Converter Module

In high-density power management applications such as portable devices, industrial automation and data centres, demands on power module size, conversion efficiency and quiescent power consumption are constantly increasing. Texas Instruments’ (TI) TPSM82902SISR, a 2A output, high-efficiency, low-quiescent current (IQ) synchronous buck converter module, offers a cost-effective power solution for space-constrained applications thanks to its MicroSiP™ package with an integrated inductor and DCS-Control™ topology. Shenzhen Mingjiada Electronics, as a seasoned distributor of electronic components, has long supplied brand-new, genuine TPSM82902SISR modules and offers high-value buyback services for the full range of TI power modules and corporate dead stock.

I. TPSM82902SISR Core Product Details and Specifications
The TPSM82902SISR belongs to the TPSM82902 series, designed specifically for a wide input voltage range and high power density. It integrates a power MOSFET and a 1µH inductor within an extremely compact package, significantly simplifying PCB layout.
Basic Description: A high-efficiency, low IQ synchronous buck DC-DC converter module with an integrated inductor, featuring an input range of 3V to 17V and a continuous output current of 2A.
TPSM82902SISR Specification Details:
Ultra-low quiescent current: typical value of just 4 µA; supports automatic PFM/PWM power-saving modes; maintains extremely high efficiency even at light loads, making it suitable for battery-powered applications.
High efficiency and low conduction losses: utilises the DCS-Control™ topology, with high-side RDS(ON) of 62 mΩ and low-side RDS(ON) of 22 mΩ; delivers excellent efficiency across a wide duty cycle and load range, and supports 100% duty cycle mode.
Package and dimensions: 11-pin MicroSiP™ (SIS) package, dimensions 3.0 mm × 2.8 mm × 1.6 mm; highly integrated with an optimised single-layer pin layout.
Output voltage configuration:
External VFB voltage divider: 0.6 V to 5.5 V
VSET internal divider: 16 fixed options (0.4V to 5.5V)
Feedback voltage accuracy of ±0.9% across the full temperature range (-40°C to +125°C).
Switching frequency and modes: Selectable 2.5MHz or 1.0MHz; supports forced PWM or automatic PFM power-saving mode (with dynamic switching); built-in automatic efficiency enhancement (AEE).
Protection and features: Precision enable input, Power-Good output, adjustable soft-start and tracking, output discharge function, no external bootstrap capacitor required.
Operating environment: −40°C to +125°C industrial-grade operating temperature, compliant with RoHS and REACH standards, MSL 2 reliability.

II. Key Application Areas
Thanks to its compact size, wide input voltage range and low IQ characteristics, the TPSM82902SISR is widely used in various systems where power density and battery life are critical:
Enterprise and Data Centres: Point-of-Load (PoL) power supply for servers, storage devices, and wired/wireless network equipment.
Industrial and Automation: Regulated power supplies for factory automation control, PLCs, machine vision and test and measurement instruments.
Wireless Communications: On-board power conversion for wireless infrastructure, RF modules and IoT gateways.
Consumer and Portable Devices: Battery- or 12V-powered products such as high-performance handheld devices, digital televisions, set-top boxes and home gateways.
