LMR36500
- Functional Safety-Capable
- Designed for rugged industrial applications:
- Junction temperature range –40°C to +150°C
- Input transient capability up to 70 V
- Wide input voltage range: 3.0 V (falling threshold) to 65 V
- Minimized switch node ringing to reduce EMI
- Adjustable and fixed output 3.3-V and 5-V voltage options available
- Designed for scalable industrial power supplies:
- Minimized design size and cost:
- Ultra-small, 2-mm × 2-mm HotRod™ package
- High efficiency across load range with low power dissipation:
- Greater than 80% peak efficiency at 1 MHz (3.3-V V OUT)
The LMR36500 is the industry smallest 65-V, 50-mA synchronous step-down DC/DC converter in 4-mm 2 HotRod package. This easy-to-use converter can handle input voltage transients up to 70 V, provide excellent EMI performance and supports fixed, 3.3 V, 5 V and other adjustable output voltages.
The LMR36500 uses a peak current mode control architecture with internal compensation to maintain stable operation with minimal output capacitance. The LMR36500 with the right resistor selection from the RT pin to ground can be externally programmed to any desired switching frequency of operation over a wide range from 200 kHz to 2.2 MHz. The precision EN/UVLO feature allows precise control of the device during start-up and shutdown. The PGOOD flag, with built-in glitch filter and delayed release, offers a true indication of the system status, eliminating the requirement for an external voltage supervisor. The compact design size and rich feature set of LMR36500 simplifies implementation for a wide range of industrial applications.
