Data sheet:
Functional safety information:
The LMR51603-Q1 is a wide-VIN, easy-to-use, synchronous buck converter capable of driving up to 300mA load current. With a wide input range of 4V to 65V, the device is designed for a wide range of industrial applications for power conditioning from an unregulated source.
The LMR51603-Q1 operates at 400kHz switching frequency to support use of relatively small inductors for an optimized design size. The LMR51603-Q1 has a pulse frequency modulation (PFM version) to realize high efficiency at light load and forced pulse width modulation (FPWM version) to achieve constant frequency and small output voltage ripple over the full load range. Soft-start and compensation circuits are implemented internally, which allow the device to be used with minimal external components.
The device has built-in protection features, such as cycle-by-cycle current limit, hiccup mode short-circuit protection, and thermal shutdown in case of excessive power dissipation.
- AEC-Q100 qualified
- Temperature grade 1: –40°C to 125°C ambient operating temperature range
- Functional Safety-Capable
- Configured for rugged industrial applications
- 4V to 65V input voltage range
- Input transient protection up to 70V
- 300mA continuous output current
- 80ns minimum switching on time
- Fixed 400kHz switching frequency
- –40°C to 150°C junction temperature range
- 96% maximum duty cycle
- Monotonic start-up with prebiased output
- Short-circuit protection with hiccup mode
- Precision enable
- Small design size and ease of use
- Integrated synchronous rectification
- Internal compensation for ease of use
- Various options in pin-to-pin compatible package
- PFM and forced PWM (FPWM) options
- Pin-to-pin compatible with the LMR16006Y-Q1, LM2842-Q1, LMR50410-Q1, and TPS560430-Q1
