LM46000EVM User Guide
1 Introduction
The Texas Instruments LM46000EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the LM46000 wide-input voltage Simple Switcher
®
buck regulator. The device offers
configurability in a 1 V to 28 V output voltage, synchronous rectification and a 200 kHz to 2.2 MHz
adjustable frequency range. It also offers external frequency synchronization, power good (PG) flag, and a
precision enable to program undervoltage lockout (UVLO) and internal compensation. The LM46000EVM
is configured for an output voltage of 3.3 V and a switching frequency of 500 kHz. Refer to the LM46000
datasheet for additional features, detailed description and available options.
The EVM contains one DC-DC converter (See Table 1).
