Описание

The TPS63805, TPS63806, and TPS63807 are high efficiency, high output current buck-boost converters. Depending on the input voltage, they automatically operate in boost, buck, or in a novel 4-cycle buck-boost mode when the input voltage is approximately equal to the output voltage.

Three pin-to-pin device options: TPS63805, TPS63806, and TPS63807 with specific application focus
Input voltage range: 1.3 V to 5.5 V
- Device input voltage > 1.8 V for start-up
Output voltage range: 1.8 V to 5.2 V (adjustable)
High efficiency over the entire load range
- Power save mode and mode selection for forced PWM-mode
Peak current buck-boost mode architecture
- Defined transition points between buck, buck-boost, and boost operation modes
- Forward and reverse current operation
- Start-up into pre-biased outputs
Safety and robust operation features
- Integrated soft start
- Overtemperature- and overvoltage-protection
- True shutdown function with load disconnect
- Forward and backward current limit
TPS63805
- Optimized for smallest solution size of 18.5 mm² (works with a 22-µF minimum output capacitor)
- 2-A output current for V_I ≥ 2.3 V, V_O = 3.3 V
- 11-µA operating quiescent current
TPS63806
- Optimized for best load step response (180-mV load-step response at a 2 A current step)
- Up to 2.5-A transient output current
- 13-µA operating quiescent current
TPS63807
- Optimized for smallest solution size of 18.5 mm² (works with a 22-µF minimum output capacitor)
- 2-A output current for V_I ≥ 2.3 V, V_O = 3.3 V
- 11-µA operating quiescent current
- Output discharge feature when EN is low
- 480-µs T_ramp for small inrush current during start-up
