■ DESCRIPTION
The FUJITSU MB3870 is a pulse width modulation (PWM) DC/DC converter IC chip that provides a selection of 1.3 V to 3.5 V output voltages for Pentium?* CPU’s, using a 5-bit input signal information.
The MB3870 utilizes synchronous rectification for high efficiency and features a soft-start/discharge control function for ease in designing power supplies in multi-supply systems, making it ideal for Pentium? II power supply systems.
■ FEATURES
? Highly efficient for using synchronous rectification scheme
? On-chip soft-start/discharge control circuit
? High precision output voltage: ±1.2
? 5-bit, 32-step DAC: 3.5 V to 2.1 V in 100 mV steps
2.05 V to 1.3 V in 50 mV steps
? Frequency range: 100 kHz to 500 kHz using variable resistance (on-chip frequency setting capacitance)
? Standby current: 0 μA TYP
? On-chip PWRGOOD circuit for output voltage state detection
? Timer-latch short-circuit protection circuit, and overvoltage protection circuit for output protection
