The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power supply solutions. The MAX17760 is a high-efficiency, high-voltage, Himalaya synchronous step-down DC-DC converter with integrated MOSFETs operating over an input-voltage range of 4.5V to 76V. The device can deliver up to 300mA current. Output voltage is programmable from 0.8V up to 88% of input voltage (VIN). Built-in control loop compensation eliminates the need for external components.The MAX17760 features a peak-current-mode control architecture. The device can be operated in either the forced pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes. Forced PWM mode provides constant frequency operation at all loads for frequency sensitive applications, while PFM mode provides superior light-load efficiency by skipping pulses. The device integrates an open drain active-low RESET output voltage monitor, adjustable input undervoltage lockout (EN/UVLO) and programmable soft-start.The feedback voltage regulation accuracy over -40°C to +125°C is +1.6% to -1.7%. The MAX17760 is available in a compact 12-pin (3mm x 3mm) TDFN package.

The MAX178 is a complete, calibrated 12-bit A/D converter (ADC) which includes a precision voltage reference, track-and-hold, and conversion clock. Internal calibration circuitry maintains true 12-bit performance over the full operating temperature range without external adjustments. In addition, each conversion includes an auto-zero cycle which reduces zero errors to typically below 100μV.CHIP SELECT, READ, and WRITE inputs are included for easy microprocessor interfacing without additional logic. 2-byte, 12-bit conversion data is provided over an 8-bit three-state output bus. Either byte may be read first. Two converter busy flags facilitate polling of the converter's status.The MAX178's analog input range is 0V to +5V when using a +5V reference. The MAX178A's internal reference accuracy is ±0.3%, while the MAX178B is intended for use with an external reference.ApplicationsAudio and Telecom ProcessingDigital-Signal ProcessingHigh-Accuracy Process ControlHigh-Speed Data Acquisition
