National's award-winning SIMPLE SWITCHER family allows you to design and optimize robust power supplies with the minimum set of external components. Supporting input voltage ranges of 3V to 75V, each SIMPLE SWITCHER series has multiple products with pin-to-pin compatibility for added design flexibility.
The newest LMZ SIMPLE SWITCHER Power Modules feature a new, innovative package, deliver best-in-class EMI and thermal performance, and provide high efficiency and a wide input voltage and load current range.
The LM2267x/LM22680 series regulators feature the lowest BOM count, the LM2557x/557x regulators feature the best transient performance, and the LM310x regulators feature the highest efficiency. The new LM315x controllers provide support for high-power output designs.
High efficiency over a wide input voltage and load current range
Pin-to-pin compatible for different load currents
Delivers the efficiency of a synchronous switching regulator with the simplicity of a linear regulator, eliminating the external inductor and layout placement challenges typical of switching regulator designs
WEBENCH Power Architect lets engineers quickly design and simulate a complete power supply system for any number of supplies and outputs. System designers can optimize the entire power supply system for small footprint, high efficiency, and cost in minutes.
National's new integrated SIMPLE SWITCHER® power modules, in additional to existing voltage regulators controllers, are also supported in WEBENCH Power Architect for low part count and small footprint with industry-leading thermal performance and low electromagnetic interference (EMI).

New SIMPLE SWITCHER® Power Module Eval & Demo Boards
The SIMPLE SWITCHER power module demonstration board is optimized for minimized board area and ease-of-use. By utilizing an integrated shielded inductor, an all ceramic capacitor design, and a minimum of external passive components placed on both sides of the PCB, the power module DEMO board shows the ultimate in high power density power supply design. The power modules also offer tremendous ease-of-use in terms of board layout requirements, only requiring a 2-layer 1oz copper PCB to complete the entire design.
Features
Integrated shielded inductor in module
Up to 96% efficiency
High full load ambient temperature operation
Precision enable & soft-start for power supply sequencing and tracking
