Texas Instruments Incorporated (TI) introduced four new SIMPLE SWITCHER power management integrated circuits for space-constrained point-of-load designs in industrial, communications and automotive applications. The National 1-A LMZ10501 and 650-mA LMZ10500 nano modules with on-chip inductor and 2-A LMR24220 and 1-A LMR24210 nano regulators feature high performance and tiny, nano packaging as small as 7.5-mm2. Used in conjunction with the WEBENCH® online design tool, the products simplify and speed the design process.
In a typical space-constrained design, TI's new nano power modules, which support an input voltage range of 2.7 V to 5.5 V, can be designed alongside the nano power regulators to step down from an intermediate voltage rail to the point of load, providing a complete power management solution in applications with space and height limitations.
The SIMPLE SWITCHER power modules comply with the CISPR 22 Class B radiated and conducted electromagnetic interference (EMI) standard for communications applications. The new nano modules also meet the CISPR 25, Class 5 radiated noise emissions standard for automotive applications. For portable applications TI also offers the 600-mA TPS82671 in a fully integrated 6.7-mm2 MicroSiP package.
The new nano power modules and regulators are available in volume now from TI and its authorized distributors. The nano power modules are offered in an 8-pin leadless surface mount package measuring 2.5 mm by 3 mm by 1.2 mm. The suggested retail price of the LMZ10501 is $1.80 and the LMZ10500 is $1.30 in 1,000-unit quantities. The nano power regulators are offered in a 28-pin micro SMD package measuring 2.45 mm by 3.64 mm by 0.60 mm. The suggested retail price of the LMR24220 is $2.00 and the LMR24210 is $1.50 in 1,000-unit quantities.
