TPSM83103
Overview
The TPSM83102 and TPSM83103 are constant frequency peak current mode control buck-boost converters in samll μSiP module package. It has a 3A peak current limit (typical) and 1.6V to 5.5V input voltage range, and provide a power supply solution for system pre-regulators and voltage stabilizers.
- 1.6V to 5.5V input voltage range - Device input voltage > 1.65V for start-up
- 1V to 5.5V output voltage range(adjustable)
- High output current capability, 3A peak switch current - 1.5A output current for VIN ≥ 3V, VOUT = 3.3V - 1.2A output current for VIN ≥ 2.7V, VOUT = 3.3V
- High efficiency over the entire load range - 8μA typical quiescent current - Automatic power save mode and forced PWM mode configurable
- Peak current buck-boost mode architecture - Seamless mode transition - Forward and reverse current operation - Start-up into pre-biased outputs - Fixed-frequency operation with 2MHz switching
- Safety and robust operation features - Overcurrent protection and short-circuit protection - Integrated soft start with active ramp adoption - Overtemperature protection and overvoltage protection - True shutdown function with load disconnect - Forward and backward current limit
- Small solution size - 2.6mm × 2.0mm × 1.2mm(max) 8-pin μSiP package VI VO VIN VOUT CI CO
