MAX1755 : The MAX1755/MAX1756 are temperature monitors with ±3°C accuracy, each with a built-in comparator and SMBus™-controlled variable trip threshold. This DACprogrammable threshold allows specific thermal zones and system responses to overtemperature conditions to be adjusted under software control. The MAX1755/ MAX1756 feature serial programmability, low cost, wide supply-voltage range, and a tiny package. The MAX1755 has a self-clearing thermostat output (OVERT), and the MAX1756 has a latched interrupt output (ALERT). A variety of slave addresses allow for up to six devices per system (Table 3). The MAX1755 has 4°C of built-in hysteresis. The MAX1756 detects both low-to-high and high-to-low temp.

MAX17551 : The MAX17551 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4V to 60V input. The converter can deliver up to 50mA and generates output voltages from 0.8V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.75% over -40°C to +125°C. The MAX17551 uses peak-current-mode control and can be operated in pulse-width modulation (PWM) or pulsefrequency modulation (PFM) modes. The device is available in a 10-pin (3mm x 2mm) TDFN and 10-pin (3mm x 3mm) μMAX® packages. Simulation models are available.

MAX17559 : The MAX17559 is a dual-output, synchronous step-down controller that drives nMOSFETs. The device uses a constant-frequency, peak-current-mode architecture. The two outputs can be configured as independent voltage rails. Input capacitor size is minimized by running the two outputs 180° out-of-phase. The IC supports current sensing using either an external current-sense resistor for accuracy or an inductor DCR for improved system efficiency. Current foldback or latchoff limits MOSFET power dissipation under short-circuit conditions. The IC provides independent adjustable soft-start/stop for each output and can start up monotonically into a prebiased output. The IC can be configured in either P.
