LM26420YSQ/NOPB
Dual 2.0A, High Frequency Synchronous Step-Down DC-DC Regulator
VIN PG2
VIN Buck 2 Compliant with CISPR25 Class5 Conducted
Emissions Input Voltage Rangeof3Vto 5.5V Output Voltage Rangeof 2-A Output Current per Regulator High Switching Frequency:
0.55 MHz (LM26420Y) 0.8V, 1.5% Internal Voltage Internal Soft Start Independent Power Good
for Each Output Current Mode, PWM Operation Thermal Shutdown Overvoltage Protection Start-up into Pre-biased Output Regulators are 180° Outof
DescriptionThe LM26420 regulator is a monolithic, high-
efficiency dual PWM step-down DC-DC converter.
This device has the abilityto drive two 2-A loads with internal 75-mΩ PMOS top switch and an internal
50-mΩ NMOS bottom switch using state-of-the-art
BICMOS technology resultsin the best power density
available. The world-class control circuitry allow on
times as low as 30 ns, thus supporting exceptionally
high-frequency conversion over the entire 3-Vto 5.5- input operating range downto the minimum output
voltageof 0.8V.
Although the operating frequencyis high, efficienciesto 93% are easyto achieve. External shutdownis
included, featuring an ultra-low standby current. The
LM26420 utilizes current-mode control and internal
compensationto provide high performance regulation
overa wide rangeof operating conditions.
