► Silent Switcher® architecture: enables a pact, efficient, low EMI solution ► PMBus/I2C serial interface ► Telemetry read back includes VOUT, IOUT, VIN, die temperature, and faults ► Programmable voltage, current limit, sequencing, soft start and stop, undervoltage and overvoltage, phase, frequency (up to 4 MHz), and loop pensation ► Integrated three times programmable NVM ► Key parameters selectable by resistor ► VOUT set point range: 0.4 V to 5.5 V ► VOUT accuracy: ±0.25%, 0.6 V ≤ VOUT ≤ 1.375 V ► Differential remote VOUT sense ► Fast transient response ► Wide VIN supply range: down to 2.9 V or 1.5 V with EXTVCC ► Programmable and synchronizable: 400 kHz to 4 MHz ► 24-lead (3.5 mm × 4 mm) LQFN package The LT7170/LT7170-1 are monolithic DC/DC synchronous stepdown regulators that deliver up to 20 A of continuous output current.
The LT7170-1 option has two switching phases that are connected to two inductors to drive a single-regulated output supply.
The quick, clean, low-overshoot switching edges deliver high efficiency while minimizing electromagnetic interference (EMI) emissions.
