LM61460-Q1 Synchronous Step-Down Converter

Texas Instruments LM61460-Q1 Synchronous Step-Down Converter is integrated with high-side and low-side MOSFETs. The converter provides up to 6A of output current and is delivered over a wide input range of 3.0V to 36V (tolerant of 42V), easing input surge protection design. The LM61460-Q1 implements soft recovery from dropout, which eliminates overshoot on the output. The LM61460-Q1 is specifically designed for minimal EMI. The device incorporates pseudo-random spread spectrum, 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 set or synchronized between 200kHz and 2.2MHz to avoid noise-sensitive frequency bands. The frequency also can be selected for improved efficiency at a low operating frequency or smaller solution size at a high operating frequency. The LM61460-Q1 is qualified for automotive AEC-Q100 grade 1 and 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.
