Additional Details

The MAX16990/MAX16992 are high-performance, current-mode PWM controllers with 4µA (typ) shutdown current for wide input voltage range boost/SEPIC converters. The 4.5V to 36V input operating voltage range makes these devices ideal in automotive applications such as for front-end “preboost” or “SEPIC” power supplies and for the first boost stage in high-power LED lighting applications. An internal low-dropout regulator (PVL regulator) with a 5V output voltage enables the MAX16990/MAX16992 to operate directly from an automotive battery input. The input operating range can be extended to as low as 2.5V when the converter output is applied to the SUP input.

There are multiple versions of the devices offering one or more of the following functions: a synchronization output (SYNCO) for two-phase operation, an overvoltage protection function using a separate input pin (OVP), and a reference input pin (REFIN) to allow on-the-fly output voltage adjustment.

The MAX16990 and MAX16992 operate in different frequency ranges. All versions can be synchronized to an external master clock using the FSET/SYNC input.

In addition, the MAX16990/MAX16992 have a factory-programmable spread-spectrum option. Both devices are available in compact 12-pin TQFN and 10-pin µMAX^® packages.

Product Detail

The MAX16990/MAX16992 evaluation kits (EV kits) are fully assembled and tested PCBs that contain a 16W DC-DC converter for front-end preboost automotive applications. The devices integrate a low-side FET driver and current-mode control-loop circuitry for output-voltage regulation, making them ideal for automotive boost or SEPIC converters. The MAX16990 integrated driver switches at 400kHz, while the MAX16992 integrated driver switches at 2.2MHz using the default configuration. The MAX16990 can be synchronized with an external clock source within the 100kHz to 1MHz range, and the MAX16992 within the 1MHz to 2.5MHz range.

The EV kits operate from a DC supply voltage of 4.5V (3V in bootstrapped mode) up to 36V. The EV kits can withstand a 42V load-dump condition for up to 400ms. Each EV kit demonstrates the device features, such as dynamic adjustable output voltage, external clock synchronization, two-phase operation configurability, cycle-by-cycle current limit, hiccup mode, and thermal shutdown. The boost converter regulates 8V and can supply a current up to 2A. Each EV kit includes an external p-MOSFET (P1) that can be used to disconnect the boost output from the load in a fault condition. The EV kits also demonstrate a reference MAX16990 design for automotive applications.
