User guide:
The TPS92205x family is a 1A / 2A non-synchronous Boost / Buck-Boost LED driver with 4.5V to 65V wide input range. By integrating the low-side NMOS, the device is capable of driving LEDs with high power density and high efficiency. The device also supports common anode anodeconnection and single layer PCB. The switching frequency is set at 400kHz or 1MHz.
The TPS92205x family support PWM dimming by configuring through the DIM input pins by means of simple high and low signals. The TPS92205x family support analog dimming by configuring through the DIM input pins by means of analog voltage signals. The device adopts an adaptive off-time current mode control along with smart and accurate sampling to enable fast PWM dimming and achieve high dimming ratio.
The TPS92205x family also provides multiple systematic protections, including LED open and short, switching FET open and short, sense resistor open and short, and thermal shutdown.
- 4.5V to 65V wide input range
- LED common anode connection
- Integrated 300mΩ MOSFET:
- Typical current limit (1.6A / 3.2A)
- Switching frequency (400kHz / 1MHz)
- Advanced dimming options:
- Analog dimming (200:1)
- Fast PWM dimming (50ns pulse width)
- Full protection features:
- LED open and short protection
- Switching FET open and short protection
- External component failure protection
- Cycle-by-cycle current limit
- Thermal shutdown
- Package: WSON-8, HVSSOP-8, SOT583
