Product Overview
LTC®3769 is a high performance single output synchronous boost converter controller that drives an all N-channel power MOSFET stage. Synchronous rectification increases efficiency, reduces power losses and eases thermal requirements, simplifying high power boost applications. The 28µA no-load quiescent current extends operating run time in battery-powered systems. A 4.5V to 60V input supply range encompasses a wide range of system architectures and battery chemistries. When biased from the output of the boost converter or another auxiliary supply, this can operate from an input supply as low as 2.3V after start-up. The operating frequency can be set within a 50KHz to 900KHz range or synchronized to an external clock using the internal PLL. The SS pin ramps the output voltage during start-up. The PLLIN/MODE pin selects Burst Mode® operation, pulse skipping mode or forced continuous mode at light loads. Typical applications are industrial, medical, military.
- Synchronous operation for highest efficiency and reduced heat dissipation
- ±1% 1.200V reference voltage, RSENSE or inductor DCR current sensing
- 100% duty cycle capability for synchronous MOSFET
- Power good output voltage monitor
- Internal LDO powers gate drive from VBIAS or EXTVCC
- Chip bias voltage operating range from 4.5 to 60V
- Feedback current is ±50nA
- 20-lead plastic SSOP package
- Temperature rating range from –40°C to 125°C
