The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power-supply solutions. The MAX17577 and MAX17578 are high-efficiency, high-voltage, inverting, Himalaya synchronous DC-DC converters with integrated MOSFETs and internal compensation. The devices generate output voltages (VOUT) from -0.9V to -36V and can deliver up to 1A of load current from a wide 4.5V to (60V - |VOUT|) input- voltage range.

The devices feature peak current-mode control architecture. The MAX17577 operates in continuous conduction mode (CCM) at all loads; thus, providing a constant frequency operation. The MAX17578 operates in discontinuous conduction mode (DCM) for superior efficiency at light loads. Low minimum on-time allows higher switching frequencies and small solution sizes.

The devices allow the EN/UVLO, active-low RESET and RT/SYNC pins to be driven by signals that are referenced to system ground, eliminating the need for external-level shifter circuits. The feedback-voltage regulation accuracy is ±1.3% over a wide -40°C to +125°C temperature range. The devices are available in a compact 12-pin (3mm x 3mm) TDFN-EP package. Simulation models are available.
