MAX15054 New high-side FET driver simplifies the design of buck and buck-boost HB LED drivers

High-voltage, high-side FET driver targets HB LED driver applications.

The MAX15054 provides a simple solution for implementing a buck or buck-boost topology in high-voltage LED designs that lack a high-side MOSFET driver.

SUNNYVALE, CA—January 27, 2010—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX15054, a high-side MOSFET driver for high voltage applications. This device provides a low-cost solution for HB (high-brightness) LED designs that require a buck or buck-boost topology, but lack the requisite high-side MOSFET driver. The MAX15054 enables designers to avoid the cost and complexity of a SEPIC topology by allowing the implementation of buck and single-inductor buck-boost topologies with the output referenced to ground in single string and multistring LED drivers.

The MAX15054 features a very short (12ns, typ) propagation delay, as well as short rise and fall times due to its 2A drive capability. Its dual UVLO (undervoltage lockout) feature protects the power MOSFET from damage in the event that the gate-drive or supply voltage is too low. Due to its operation up to 60V, the MAX15054 can be used by designers for automotive and HB LED illumination applications. It is also well suited for full- and half-bridge and two-switch forward converters in datacom, telecom, and server applications.

The MAX15054 is available in a small, 2.9mm x 2.8mm, 6-pin SOT23 package, and is fully specified over the -40°C to +125°C automotive temperature range. Prices start at $0.42 (1000-up, FOB USA).

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells high-performance semiconductor products. The Company was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers' products. To date, it has developed over 6200 products serving the industrial, communications, consumer, and computing markets.
