The LMQ61460-Q1 is a high-performance, DC-DC synchronous buck converter with integrated bypass capacitors. With integrated high-side and low-side MOSFETs, up to 6A of output current is delivered over a wide input range of 3.0V to 36V; 42V tolerance supports load dump for durations of 400ms. The device implements soft recovery from dropout eliminating overshoot on the output.
The LMQ61460-Q1 is designed with mitigated interference and noise technology using architecture 2 features (MINT 2) to quickly and easily implement a low-EMI design. The device incorporates pseudo-random spread spectrum, integrated bypass capacitors, adjustable SW node rise time, low-EMI VQFN-HR package featuring low switch node ringing, and optimized pinout for ease of use. The switching frequency can be synchronized between 200kHz and 2.2MHz to avoid noise sensitive frequency bands. In addition, the frequency can be selected for improved efficiency at low operating frequency or smaller design size at high operating frequency.
Auto-mode enables frequency foldback when operating at light loads, allowing an unloaded current consumption of only 7µA (typical) and high light load efficiency. Seamless transition between PWM and PFM modes, along with very low MOSFET ON resistances and an external bias input, makes sure of exceptional efficiency across the entire load range.
The device is available in a 14-pin VQFN-HR package with wettable flanks. Electrical characteristics are specified over a junction temperature range of –40°C to +150°C. Find additional resources in the Related Documentation.
