Mingjiada Supply TI TPSM83100 1.5A MicroSiP™ Buck-Boost Power Module With Integrated Inductor

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the TI TPSM83100 power module. This device is a 1.5A buck/boost power module in a MicroSiP™ package with an integrated inductor, suitable for single-cell lithium batteries, portable devices, USB power supply applications and space-constrained embedded systems.

Product Overview: From Discrete Solutions to Integrated µSiP Power Modules
The TPSM83100 is a 1.5A buck/boost power module launched by TI, utilising a MicroSiP™ package with an integrated inductor. The device supports a wide input voltage range and adjustable output voltage, and is capable of operating in buck, boost and buck-boost transition modes to provide a stable power supply to the load.
For space-constrained portable devices and embedded boards, the TPSM83100’s modular design reduces the footprint of external inductors and compensation networks, simplifying the power tree design. Its 1.5A output capability is suitable for powering sensors, wireless modules, MCUs, logic circuits and low-power peripherals.

Key Features: Seamless Mode Switching, True Shutdown and Comprehensive Protection Chain
The TPSM83100 employs peak current-mode control, automatically switching between buck, pass-through, boost and 3-cycle buck-boost modes based on the relative relationship between the input and output voltages. Mode entry and exit are defined by clear duty cycle thresholds, preventing repeated oscillation when input and output voltages approach critical points. This reduces output voltage ripple, ensuring that typical rails—such as 3.3V, where the battery voltage may cross the output voltage—operate smoothly throughout the entire discharge curve.
In terms of safety and reliability, the module integrates overcurrent protection, short-circuit protection, over-temperature protection and overvoltage protection, and employs an integrated soft-start with active ramping to suppress inrush current. It also supports start-up to a pre-biased output, allowing a voltage to be present at the output prior to chip enable without causing reverse current flow. The shutdown function provides true load disconnection capability whilst offering both forward and reverse current limiting, which is of practical value in backup scenarios where power must be supplied in reverse from a backup battery or supercapacitor to the main system. The TPSM83101’s additional active output discharge feature actively pulls the output voltage down to near-ground potential when EN is pulled low, meeting the power-down timing requirements of certain port specifications or downstream chips.

Typical application scenarios: high-density power supplies ranging from wearables to industrial sensors
Single-cell lithium-ion portable devices: as the battery voltage fluctuates with charge level, the TPSM83100 can switch between buck and boost modes to provide a stable power rail for the system.
Power banks and USB-powered devices: Suitable for low-power boost/buck power supply scenarios with USB or battery input.
Wearables and IoT devices: The compact MicroSiP™ package is ideal for space-constrained wireless sensors, smart wearables and portable medical devices.
Embedded microprocessor systems: Provides a compact power supply solution for auxiliary power rails of MCUs, DSPs and FPGAs, as well as digital logic circuits.
Test and portable instruments: Battery-powered portable test equipment can utilise its wide input range and stable output to simplify power tree design.
Wireless communication modules: Provides stable power supply for low-power wireless modules such as Wi-Fi, Bluetooth and LoRa.

In battery-powered and space-constrained electronic systems, buck/boost power modules must maintain a stable output across a wide input range whilst balancing size, efficiency and design complexity. With a 1.5A output capability, MicroSiP™ integrated inductor packaging and a buck/boost architecture, the TI TPSM83100 provides a compact power solution for portable devices, IoT endpoints and embedded systems.
