- 15 µA in active mode with no load (typical)
- Wide voltage conversion range:
- tON-MIN = 60 ns (typical)
- tOFF-MIN = 70 ns (typical)
- Low MOSFET ON-resistance:
- RDS_ON_HS = 53 mΩ (typical)
- RDS_ON_LS = 31 mΩ (typical)
- Adjustable frequency range: 350 kHz to 2.2 MHz
- Pin-selectable auto mode or forced PWM mode
- Start-up into pre-biased load, fixed or adjustable soft-start time, and tracking
- Synchronizable to external clock, internal compensation, power-good flag, and precision enable
- Cycle-by-cycle current limiting, hiccup, UVLO, and thermal shutdown protections
- Create a custom design with the WEBENCH power designer using LM73605-Q1 or LM73606-Q1
The LM73605-Q1/LM73606-Q1family of devices are easy-to-use synchronous step-down DC/DC converters capable of driving up to 5 A (LM73605-Q1)or 6 A (LM73606-Q1) of load current from a supply voltage ranging from 3.5 V to 36 V. The LM73605-Q1/LM73606-Q1 provide exceptional efficiency and output accuracy in a very small solution size. Peak current-mode control is employed. Additional features such as adjustable switching frequency, synchronization to an external clock, power-good flag, precision enable, adjustable soft start, and tracking provide both flexible and easy-to-use solutions for a wide range of applications. Automatic frequency foldback at light load and optional external bias improve efficiency over the entire load range. The family requires few external components and has a pinout designed for simple PCB layout with optimal EMI and thermal performance. Protection features include thermal shutdown, input undervoltage lookout, cycle-cy-cycle current limiting, and hiccup short-citcuit protection. The LM73605-Q1 and LM73606-Q1 devices are pin-to-pin compatible for easy current scaling.
