SEPIC Controllers General Description Benefits and Features The MAX16990/MAX16992 are high-performance, Minimized Radio Interference with Switching current-mode PWM controllers with 4 A (typ) shut- Frequency Above the AM Radio Band down current for wide input voltage range Boost /SEPIC Space-Efficient Solution Design with Minimized converters. The to 36V input operating volt- External Components age range makes these devices ideal in automotive 100kHz to 1 MHz (MAX16990) and 1 MHz to applications, such as front-end preboost or SEPIC (MAX16992) Switching-Frequency Ranges power supplies and for the first Boost stage in high- 12-Pin TQFN (3mm x 3mm) and 10-Pin MAX.

2 Power LED lighting applications. An internal low-dropout Packages regulator (PVL regulator) with a 5V output voltage enables the MAX16990/MAX16992 to operate directly Spread Spectrum Simplifies EMI Management Design from an automotive battery input. The input operating Flexibility with Available Configurations for Boost , range can be extended to as low as when the SEPIC, and Multiphase Applications converter output is applied to the SUP input. Adjustable Slope Compensation Current-Mode Control There are multiple versions of the devices offering one Internal Soft-Start (9ms).

3 Or more of the following functions: a synchronization output (SYNCO) for two-phase operation, an overvoltage Protection Features Support Robust Automotive protection function using a separate input pin (OVP), and Applications a reference input pin (REFIN) to allow on-the-fly output Operating Voltage Range Down to ( or voltage adjustment. Lower in Bootstrapped Mode), Immune to Load-Dump Transient Voltages Up to 42V. The MAX16990 and MAX16992 operate in different PGOOD Output and Hiccup Mode for Enhanced frequency ranges. All versions can be synchronized to an System Protection external master clock using the FSET/SYNC input.

4 Overtemperature Shutdown In addition, the MAX16990/MAX16992 have a factory- -40 C to +125 C Operation programmable spread-spectrum option.
