TPS61305 Overview
Key Specifications
Package: BGA
Pins: 20
Operating Voltage: 5.5 V
Height: 625 µm
Description
The TPS6130xx device is based on a high-frequency synchronous boost topology with constant current sinks to drive up to three white LEDs in parallel (400‑mA, 800-mA, and 400-mA maximum flash current). The extended high-current mode (HC_SEL) allows up to 1025-mA, 2050-mA, and 1025-mA flash current out of the storage capacitor.
Key Features
- 1 Four Operational Modes – DC Light and Flashlight – Voltage Regulated Converter: 3.8 V to 5.7 V – Standby: 2 μA (Typical)
- Storage Capacitor Friendly Solution
- Automatic VF and ESR Calibration
- Power-Save Mode for Improved Efficiency at Low Output Power, Up to 95% Efficiency
- Output Voltage Remains Regulated When Input Voltage Exceeds Nominal Output Voltage
