Description

General part information

LMR36506-Q1 Series

The LMR36506-Q1 is the industry’s smallest 65 V, 0.6 A synchronous step-down DC/DC converter in 2-mm x 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, 5 V and other adjustable output voltages.

The LMR36506-Q1 uses peak current mode control architecture with internal compensation and maintains stable operation with minimal output capacitance. The wide input operating range of the LMR36506-Q1 helps it remain functional during a deep input voltage sag condition, making it an excellent choice for automotive applications withstanding severe cold crank start impulses. The PGOOD flag in the LMR36506-Q1 provides precise indication of the output voltage status, eliminating the requirement for an external supervisor. A seamless transition from FPWM to PFM, with an ultra-low standby quiescent current allows the LMR36506-Q1 to support much higher system efficiency at low output loads. The MODE/SYNC pin variant helps to synchronize the LMR36506-Q1 to an external clock. With the right resistor selection, the LMR36506-Q1 RT pin variant can also be externally programmed to any desired switching frequency of operation. The rich feature set of the LMR36506-Q1 is designed to simplify implementation for a wide range of automotive end equipments.
