DEMO MANUAL DC2016A LTM8054 36V , 5.4A Buck-Boost IN Module Regulator Description Demonstration circuit 2016A features the LTM8054, a DC2016A provides output current monitoring and a clock synchronous buck-boost Module regulator that accepts output. Input current monitoring and regulation requires input voltages lower, higher or the same as the output, the installation of a current sense resistor. The SV input IN but is also highly efficient due to its four-switch archi- for controller power can be made a diode-OR of power tecture. The output for DC2016A is 12V and the input V and the output voltage to extend the operating range IN voltage range is 6V to 35V see the LTM8054 data sheet of power V to lower voltages. There are places to mount IN for application circuits with input voltages up to 36V. optional components that add an LC input filter and also a The maximum output current of DC2016A is 3A and the unity gain buffer to operate multiple DC2016As in parallel. switching frequency is 600kHz. The LTM8054 data sheet must be read in conjunction with DC2016A supports the adjustable and controllable features this demo manual to properly use or modify DC2016A. of the LTM8054 including output voltage and current Design files for this circuit board are available at regulation, switching frequency, RUN threshold, soft- DEMO MANUAL DC2016A p s Specifications are at T = 25C A PARAMETER CONDITIONS MIN TYP MAX UNITS Minimum Input Voltage, V 6 V IN Maximum Input Voltage, V 35 V IN Maximum Output Current, I 12V < V < 35V, CTL = OPEN 3 A OUT IN V = 6V, CTL = OPEN 1.8 A IN Input Turn-On Voltage, V R10 = 332k, R11 = 121k, V Rising 5.5 V IN IN Input Turn-Off Voltage, V R10 = 332k, R11 = 121k, V Falling 4.5 V IN IN Output Voltage, V 100mA < I < 3A (See Figure 2), R2 = 11k 11.7 12.5 V OUT OUT 1%, R3 = 100k 1%, R4 = 0.015 Efficiency V = 24V, I = 3A 92 % IN OUT Switching Frequency R1 = 36.5k 600 kHz Output Current Limit R4 = 0.015 3.6 A dc2016af 2 ummary erformance
