Overview
| Topology | Boost Converter |
| Input voltage | 1.8-5.5 V |
| Switching frequency | 1800-2200 kHz |
| Output 1 | 5.5 V / 2 A |
| IC revision | 2.1 |
Description
The TS32101 is a DC/DC synchronous switching BoostConverter with fully integrated power switches, internal PWMcurrent mode compensation, and full fault protection. Theswitching frequency of 2 MHz was chosen to enable the useof small external components for portable applications. Thedevice also has a constant output current limit loop to providea sharp output current limit that doesn’t move significantlywith input voltage and output voltage.
Features
- Output up to 1.5A at 5.0V with 1.8V input
- Wide input voltage range: 1.75V – 5.5V
- Output current up to 2A
- Robust operation during hot-load disconnect and hotloaddisable
- Adjustable output voltage up to 5.5V
- Adjustable output current limit
- Includes full output isolation/reverse current blockingwhen disabled
- 2 MHz ± 10% fixed switching frequency
- Low power mode
- High efficiency – up to 95%
- Full protection for over-current, over-temperature, VOUTover-voltage, and VIN under-voltage
- Power good/fault indication
Typical applications
- USB power
- Emergency chargers
- Portable products
- Wireless remote sensors
