The LM25190 is an 42V, ultra-low IQ, synchronous buck DC/DC controller with Constant-Current Constant-Voltage (CC-CV) regulation. The controller uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation. The integrated CC-CV operation features a high accuracy for the regulation of both voltage (±1%) and current (±3%) . The CC-CV operation also provides seamless transition between constant-current and constant-voltage mode. The CC-CV operation effectively reduces the Bill Of Materials (BOM) count and cost for applications that require average output current control. The output current limit is programmable and can be dynamically changed. The LM25190 has an output current monitor.
The LM25190 has a unique EMI (Electromagnetic Interference) reduction feature known as Dual Random Spread Spectrum (DRSS). Combining low-frequency triangular and high-frequency random modulations mitigates EMI disturbances across lower and higher frequency bands, respectively. This hybrid technique aligns with the multiple resolution bandwidth (RBW) settings specified in industry-standard EMC tests.
Additional features of the LM25190 include 150°C maximum junction temperature operation, user-selectable diode emulation for lower current consumption at light-load conditions, open-drain power-good flag for fault reporting and output monitoring, precision enable input, monotonic start-up into prebiased load, integrated dual-input VCC bias supply regulator, internal 2.75ms soft-start time, and thermal shutdown protection with automatic recovery.
The LM25190 controller comes in a 3.5mm × 4.5mm, thermally enhanced, 19-pin VQFN package.
