TPS61032RSAR – 5V 3.6A Step-Up DC-DC Converter – Texas Instruments
Optimize your power management with the TPS61032RSAR synchronous boost regulator from Texas Instruments. This high-efficiency DC-DC switching IC delivers a stable 5V output from input voltages as low as 1.8V, making it ideal for space-constrained, battery-powered designs. PCX supplies this active-component solution with guaranteed authenticity and same-day shipping.
Key Features
Topology: Step-Up (Boost) Regulator
Fixed Output: 5V (±2% accuracy)
Input Range: 1.8V to 5.5V
Output Current: Up to 3.6A (switch current)
Efficiency: Synchronous rectification (up to 95%)
Switching Frequency: 600kHz (enables compact designs)
Temperature Range: -40°C to +85°C

Technical Specifications
This monolithic IC integrates a high-side MOSFET (36mΩ) and synchronous rectifier in a thermally enhanced QFN package. The current-mode control architecture ensures stable operation across line/load variations with internal soft-start and cycle-by-cycle current limiting. Minimal external components are required thanks to fixed-frequency PWM control and internal compensation.
Typical Applications
Li-ion battery charging systems
USB Power Delivery (PD) peripherals
Portable medical devices
IoT sensors
