Product Overview
LTC3787 is a high performance PolyPhase® single output synchronous boost converter controller that drives two N-channel power MOSFET stages out-of-phase. Multiphase operation reduces input and output capacitor requirements and allows the use of smaller inductors than the single-phase equivalent. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, enabling high power boost applications. It is widely used in application such as industrial, automotive, medical, military etc.
- Chip bias voltage operating range is 4.5V to 38V
- Output voltage upto 60V
- ±1% 1.200V reference voltage
- RSENSE or inductor DCR current sensing
- 100% duty cycle capability for synchronous MOSFET
- Low quiescent current (sleep mode) is 135μA typical
- Synchronizable frequency is 75KHz to 850KHz
- Programmable fixed frequency is 50KHz to 900KHz
- Power good output voltage monitor, low shutdown current is 8µA typical
- Operating temperature is -40°C to 125°C, packaging style is 28-lead plastic QFN
