Texas Instruments LM5140-Q1 | Demoboard LM5140RWGEVMHD

Description

The LM5140-Q1 High Density evaluation module helps designers to evaluate the operation andperformance of the LM5140-Q1 synchronous buck controller. The EVM operates over the input voltagerange of 3.8 V to 42 V. The EVM provides two independent outputs, a 3.3-V output with a maximum loadcurrent of 5 A, and a 5-V output with a maximum load current of 5 A. The device offers configurability andcan be setup to switch at 440 kHz or 2.2 MHz.

Features

• The LM5140-Q1 is qualified to AEC-Q100 grade 1 (-40ºC to +125ºC operating junction temperature)
• VIN 3.8 V to 42 V (EVM)
• Two outputs:– VOUT1 fixed 3.3 V, 5 V, or adjustable from 1.5 V to 15 V– VOUT2 fixed 5 V, 8 V, or adjustable from 1.5 V to 15 V
• Shutdown Mode IQ: 9 μA
• Low IQ Standby: 35 μA typical (1-channel in regulation, no load)
• The outputs can be synchronized to an external clock
• A SYNC output
• A fixed 2.2 MHz, or 440-kHz oscillator frequency
• EN1 enables Output 1
• EN2 enables Output 2
• Hiccup Mode for sustained overload
• Independent power good (PG1 and PG2) signals
• Gate drive with slew rate control for reduced EMI
• Diode Emulation or forced pulse-width modulation (FPWM)
