Product Details
The Himalaya series of voltage regulator ICs, power modules, and chargers enable cooler, smaller, and simpler power-supply solutions. The MAX17579 and MAX17580 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 300mA of load current from a wide 4.5V to (60V-|VOUT|) input-voltage range.
The devices feature peak current-mode control architecture. The MAX17579 operates in continuous conduction mode (CCM) at all loads, thus, providing a constant frequency operation. The MAX17580 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.
Applications
- Industrial Control Power Supply
- General Purpose Point-of-Load
