PISCES II DC/DC CONVERTERS
48V Input – 1.8VDC – 60A Output
G2PW1V860 – ¹/4 Brick Pisces II Series
• Industry standard pinout and footprint
• Very low dissipation
• No heat sink required for most applications
• Low profile, 0.38"
• High efficiency: 90% at 1.8V, 60A; 91% at 1.8V, 30A
• Very low common-mode noise for a commercial DC/DC converter
• Two-stage input filter
• Constant switching frequency
• Remote sense, wide trim range
• Single board design, very low parts count
• Optional baseplate or low profile heat sink for improved thermal performance
• Header with M3 metal inserts for mechanical connection to PCB

** T (Tuned Model) Option
Designed for higher di/dt and ∆l
applications, the transient response has
been modified to take advantage of the
capacitance on the customer’s PCB. This
unit requires a minimum load capacitance
of 5600µF with an impedance magnitude
of less than 0.005Ω at 15kHz. It offers
a minmum 3X improvement in the peak
response compared to a standard unit.
