6-PAKs 6-PAK POWER ELECTRONICS DIVISION SERIES PROGRAMMABLE DC/DC CONVERTER www.cdtechno.com POWER: 6 Amp click on Power Electronics Parrallelable Boost Modules SIZE: 2.00” x 0.60” x .27” PRODUCT DATA SHEET DESCRIPTION The 6-PAK™ is a modular system of control and boost SIPs. Each 6A control SIP can also drive up to 8 additional 6A boost SIPs in parallel, for a total of 54A. Each SIP accepts a regulated 5V input (+10%) and provides 2.5V to 3.6Vdc output. The circuit is optimized for high efficiency and fast load transient response needed by telecom, DSP and microprocessor applications. FEATURES Advanced thermal design, monolithic power circuitry and � Small SIP Design synchronous rectification result in outstanding performance � Parallelable Boost SIP and value. With integrated input filter and output capacitors, One stocking part meets a variety of loads the 6-PAK system makes a complete power supply which � Programmable Control SIP requires no external components over the specified Control/Boost Pair extremely configurable operating range. Pins are staked for wave solderability. � Fast Transient Response No need for large external capacitors Extremely small footprint � Low Component Count Low cost, high reliability � Staked Pins Wave solderable � Integrated Input Filter Low input ripple APPLICATION NOTE � DCAN-34 - 6-PAK Demo Board Downloadable from our website - cdpowerelectronics.com Ordering Information Typical examples: 6P 25 - CA 6A Control SIP 6P 25 - P 6A Power Booster SIP 6-PAK 8/2001 REV F Page 1 Electrical Specifications Unless otherwise specified, operating conditions are as follows: Vo = 3.3V, TA = 25°C, Cin = 100μF Parameter Conditions Min Typ Max Units Input Input Voltage Vin 4.5 5.0 5.5 VDC Input Current Ripple Vin = 4.5V to 5.5V, Io = 6A 400 mARMS Required Capacitance Cin Note 1 0 100 μF Output Output Voltage Vo Nominal 3.25 3.3 3.35 VDC Output Program Range Note 2 2.5 3.6 VDC Output Current Io T = 60°C 0 6 Amps A Output Ripple 20Mhz BW 50 75 mVp-p Output Rise Time T r Vin = 5V, Io = 6A Resistive, Co = 0 430 500 µS Output Start-Up Time T r Vin = 5v, Io = 6A Resistive, CO = 5000µF 3.0 4.0 mS Output Capacitance Range Co 0 5000 μF Line Regulation Io = 6A +0.2 +0.5 % Load Regulation Io min - Io max, Vin = 4.5-5.5V +0.8 +1.2 % Temperature Coefficient TA = -40°C to +60°CVin = 5V, IO = 6A +0.01 %/°C Combined Variation Vin min-max &/or Io min-max TA= -40°C to +60°C +2 % Protection Note 3 General Switching Frequency 800 kHz Dynamic Response ΔI O/Δt = 1A/10µsec, Vi = 5.0V, TA = 25°C Load Change from I O = 0% to IO = 100% Peak Deviation 20 30 mV Settling time (VO<10% Peak Deviation) 130 200 μsec Load change from I O = 100% to I O = 0% Peak Deviation 20 35 mV Settling time (VO<10% Peak Deviation) 200 300 μsec Temperature Operating T emperature -40 +60 °C Storage Temperature -40 +125 °C Notes 1.
