3 Description
The LM5190-Q1 is an 80V, 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 (±
4.5%) . The CC-CV operation also provides seamless
transition between constant-current and constantvoltage
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 LM5190-Q1 has an
output current monitor.
The LM5190-Q1 has a unique EMI 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 LM5190-Q1 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 LM5190-Q1 controller comes in a 3.5mm ×
4.5mm, thermally enhanced, 19-pin VQFN package
with wettable flank pins to facilitate optical inspection
during manufacturing.
