The LTC3770EG is a fast, no RSENSE step-down synchronous controller manufactured by Analog Devices. It is designed for power management applications, specifically within the DC DC switching controller category.
Key electrical characteristics include an internal VCC voltage range of 4.7V to 5.3V over a 6V to 30V input, with load regulation typically within ±2%. The device features a phased-locked loop (PLL) with an input resistance of 50 kΩ and a phase detector output current capability of ±15 μA. The PGOOD output has configurable thresholds, with an upper threshold typically at 10% (VFB Rising) and a lower threshold typically at -10% (VFB Falling), featuring a hysteresis typically of 3%.
This controller operates within a temperature range of -40°C to 85°C. The specifications are guaranteed over the full operating temperature range, assured by design and statistical process controls. The device is suitable for applications requiring efficient step-down voltage conversion with advanced control features like margining and tracking.
The internal VCC voltage is typically 5V, with a range of 4.7V to 5.3V over a 6V to 30V input.
The LTC3770EG operates over a temperature range of -40°C to 85°C.
The PGOOD upper threshold, when VFB is rising, is typically 10%, with a range of 7% to 13%.
The PGOOD lower threshold, when VFB is falling, is typically -10%, with a range of -13% to -7%.
The PGOOD hysteresis, when VFB is returning, is typically 3%, with a range of 1.5% to 3%.
The PGOOD low voltage is typically 0.4V, with a range of 0.15V to 0.4V when IPGOOD is 5mA.
