The TPS61236PRWLR is a high-current, high-efficiency synchronous boost converter from Texas Instruments (TI), designed for portable and battery-powered applications. Operating at a 1 MHz switching frequency, it supports input voltages from 2.3 V to 4.9 V and delivers adjustable output voltages between 2.9 V to 5.5 V, with a maximum output current of 8 A (peak) and sustained currents up to 3.5 A for 3.3–5 V applications.

Key features include:

• Integrated 14 mΩ/14 mΩ power switches for high efficiency (up to 97%), minimizing heat dissipation.
• Programmable constant output current to control power delivery, reducing external components and system complexity.
• Ultra-low quiescent current (10 μA at light loads) and <1 μA shutdown mode with "True Shutdown" (output disconnected from input).
• Robust protection: overvoltage, overcurrent, overtemperature, and reverse-current blocking.
• Compact 2.5 mm × 2.5 mm VQFN-9 package, ideal for space-constrained designs.

Applications include power banks, USB chargers, IoT devices, and battery-operated systems such as tablets and wearables. Its wide operating temperature range (-40°C to 125°C) ensures reliability in industrial and consumer electronics. The TPS61236PRWLR simplifies design with minimal external components, making it a cost-effective solution for high-current boost applications.
