LM26400YDual 2A, 500kHz Wide Input Range Buck Regulator | Power Management (PMIC) | 6 | Active | The LM26400Y device is a monolithic, two-output fixed-frequency PWM step-down DC-DC regulator, in a 16-pin WSON or thermally-enhanced HTSSOP package. With a minimum number of external components and internal loop compensation, the LM26400Y is easy to use.
The ability to drive 2-A loads with an internal 175-mΩ NMOS switch using state-of-the-art 0.5-µm BiCMOS technology results in a high-power density design. The world class control circuitry allows for an ON-time as low as 40 ns, thus supporting high-frequency conversion over the entire input range of 3 V to 20 V and down to an output voltage of only 0.6 V. The LM26400Y utilizes peak current-mode control and internal compensation to provide high-performance regulation over a wide range of line and load conditions. Switching frequency is internally set to 500 kHz, optimal for a broad range of applications in terms of size versus thermal tradeoffs.
Given a nonsynchronous architecture, efficiencies above 90% are easy to achieve. External shutdown is included, enabling separate turnon and turnoff of the two channels. Additional features include programmable soft-start circuitry to reduce inrush current, pulse-by-pulse current limit and frequency foldback, integrated bootstrap structure, and thermal shutdown.

LM26420-Q1Dual 2 A, automotive-qualified, high-efficiency synchronous DC/DC converter | DC/DC & AC/DC (Off-Line) SMPS Evaluation Boards | 15 | Active | The LM26420-Q1 regulator is a monolithic, high-efficiency dual PWM step-down DC/DC converter. This device has the ability to drive two 2A loads with an internal 75mΩ MOS top switch and an internal 50mΩ MOS bottom switch using state-of-the-art BICMOS technology results in the best power density available. The world-class control circuitry allow on times as low as 30ns, thus supporting exceptionally high-frequency conversion over the entire 3V to 5.5V input operating range down to the minimum output voltage of 0.8V.
Although the operating frequency is high, efficiencies up to 93% are easy to achieve. External shutdown is included, featuring an ultra-low standby current. The LM26420-Q1 uses current-mode control and internal compensation to provide high performance regulation over a wide range of operating conditions.
Because the switching frequency is made sure to be greater than 2MHz, the LM26420-Q1 can be used in automotive applications without causing interference in the AM frequency band.
