Click here to ask about the production status of specific part numbers. MAX17577, MAX17578 4.5V to 60V, 1A High-Efficiency, Synchronous,
Inverting Output DC-DC Converters General Description Benefits and Features 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. ● Reduces External Components and Total Cost
• Synchronous Operation
• All-Ceramic Capacitors, Compact Layout
• Internal Loop Compensation
• System Ground Referenced I/O Pins (EN/UVLO,
RESET) 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, 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 package. Simulation models are available. Applications
