1.The uP6128A/B is a high performance synchronous-rectified buck controller specifically designed for POL voltage regulation in notebook PC application. The controller operates with 5V bias voltage and converts 2V~26V input voltage to 0.75V~5.5V output voltage. 2. The uP6128A/B adopts constant-on-time PWM scheme that features easy-to-use, low external component count, fast transient response and quasi constant frequency operation over the operation range. Selectable Forced Continuous Conduction Mode (FCCM) or Power Saving Mode (PSM) enables the flexibility for low noise operation or high efficiency conversion over wide output current range. 3. Lossless current sensing by RDS(ON) of lower switch achieves programmable over current protection. Other features include internal soft start, integrated bootstrap diode and thermal shutdown. The uP6128A is available in WQFN3x3 -16L and WQFN4x4-16L packages. 4. The uP6128B is available in VQFN3.5x3.5- 14L and TSSOP- 14L packages. 1. Wide Input Voltage Range 2V ~ 26V 2. Wide Output Voltage Range 0.75V ~ 5.5V, 1.0% Initial Accuracy 3. Constant On Time PWM : Quasi Constant Switching Frequency; Adjustable Frequency from 200kHz to500kHz; Ultra Fast Transient Response 4. Integrated Bootstrap Diode 5. Integrated MOSFET Drivers with Shoot-Through Protection 6. Configurable Forced Continuous Current Mode or Power Saving Mode 7. Lossless, Programmable Overcurrent Protection Use Low-Side MOSFET RDS(ON) 8. Internal Soft Start 9. Over Voltage and Under Voltage Protection 10. Power OK Indication 11. WQFN4x4 - 16L, WQFN3x3 - 16L, VQFN3.5X3.5 - 14L, or TSSOP - 14L Packages 12. RoHS Compliant and 100% Lead Free |
