LMR36506RFRPER General Description

The LMR36506 is the industrys smallest 65 V, 0.6 A synchronous step-down DC/DC converter in 2-mm × 2-mm HotRod package. This easy-to-use converter can handle input voltage transients up to 70 V, provide excellent EMI performance and support fixed 3.3 V and other adjustable output voltages. The transient tolerance reduces the necessary design effort to protect against input overvoltage and meets the surge immunity requirements of IEC 61000-4-5.

The LMR36506 uses the peak current mode control architecture with internal compensation to maintain stable operation with minimal output capacitance. The LMR36506 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 the start-up and shutdown. The power-good flag, with built-in glitch filter and delayed release, offers a true indication of the system status, eliminating the requirement for an external supervisor. The compact solution size and rich feature set of LMR36506 simplifies implementation for a wide range of industrial applications.

Key Features

Designed for rugged industrial applications:
- Junction temperature range –40°C to +150°C
- Input transient protection up to 70 V
- Wide input voltage range: 3.0 V (falling threshold) to 65 V
- Low EMI and minimized switch node ringing
- Adjustable fixed output voltage options available
Suited for scalable industrial power supplies:
- Pin compatible with LMR36503 (65 V, 300 mA)
- Adjustable switching frequency: 200 kHz to 2.2 MHz with RT pin variant
Minimized solution size and cost:
- Highest power density with internal compensation and reduced external component count
- Ultra-small, 2-mm × 2-mm HotRod™ package with wettable flanks
High efficiency across load range with low power dissipation:
- 93% peak efficiency at 400 kHz (12 V_IN, 3.3 V_OUT fixed)
- 90% peak efficiency at 400 kHz (24 V_IN, 3.3 V_OUT fixed)
Ultra-low operating quiescent current at no load
- 4 µA at 24 V_IN to 3.3 V_OUT (fixed output option)
Use TPSM365R6 module for faster time to market
