ZHCSI01C April 2018 – October 2019 LMR36006
The LMR36006 is a synchronous peak-current-mode buck regulator designed for a wide variety of industrial applications. The regulator automatically switches modes between PFM and PWM depending on load. At heavy loads, the device operates in PWM at a constant switching frequency. At light loads the mode changes to PFM, with diode emulation allowing DCM. This reduces the input supply current and keeps efficiency high. The device features internal loop compensation which reduces design time and requires fewer external components than externally compensated regulators.
The LMR36006 is designed with a flip-chip or HotRod™ technology, greatly reducing the parasitic inductance of pins. In addition, the layout of the device allows for reduction in the radiated noise generated by the switching action through partial cancellation of the current generated magnetic field. As a result the switch-node waveform exhibits less overshoot and ringing.
