Introduction
LM61460 is a high-performance DC/DC synchronous buck converter. The device features integrated high-side and low-side MOSFETs, capable of delivering up to 6A output current over a wide input voltage range of 3.0V to 36V, with 42V transient voltage tolerance that simplifies input inrush protection design. The LM61460 provides soft recovery of voltage drops, eliminating output overshoot.
The LM61460 is specifically designed to reduce EMI. The device features adjustable SW node rise time and low EMI, and adopts a VQFN-HR package with low switching node ringing and an easy-to-use, optimized pin layout. The switching frequency can be set or synchronized in the range of 200kHz to 2.2MHz to avoid noise-sensitive frequency bands. The frequency can also be selected to improve efficiency at lower operating frequencies or reduce solution size at higher operating frequencies.
Auto mode enables frequency foldback during light-load operation, achieving a no-load current consumption of only 7μA (typical) and high light-load efficiency. Seamless transitions between PWM and PFM modes, combined with ultra-low MOSFET on-resistance and an external bias input, ensure excellent efficiency across the full load range.
The electrical characteristics are rated for a junction temperature range of -40°C to +150°C.
Features

- VOUT adjustable from 1V to 95% of VIN
- 0.4V dropout voltage (typical) at 4A load
- Protection features: thermal shutdown, input undervoltage lockout, cycle-by-cycle current limiting, and hiccup short-circuit protection
- High-efficiency power conversion across all load conditions
- 7μA no-load current at 13.5VIN, 3.3VOUT
- 83% PFM efficiency at 1mA, 13.5VIN, 5VOUT
- Low MOSFET on-resistance: RDS_ON_HS = 41mΩ (typical), RDS_ON_LS = 21mΩ (typical)
- External bias option for improved efficiency
- Scalable power supply compatible
- Pin-compatible with: LM61440-Q1 (36V, 4A, adjustable fSW), LM61440 (36V, 4A, adjustable fSW), LMQ61460 (36V, 6A, internal capacitor)
