Product Overview
LTC3417 is a dual constant frequency, synchronous step-down DC/DC converter. Each output voltage is adjustable from 0.8V to 5V. Internal synchronous low RDS(ON) power switches provide high efficiency without the need for external schottky diodes. A user selectable mode input allows the user to trade off ripple voltage for light load efficiency. Burst Mode® operation provides high efficiency at light loads, while Pulse Skip mode provides low ripple noise at light loads. A phase mode pin allows the second channel to operate in-phase or 180° out-of-phase with respect to channel 1. Out-of-phase operation produces lower RMS current on VIN and thus lower RMS derating on the input capacitor. It is widely used in application such as PDAs/palmtop PCs, digital cameras, cellular phones, PC cards, wireless and DSL modems etc.
- 1.4A/800mA guaranteed minimum output current
- Oscillator frequency is 1.5MHz typical at (VFREQ = VIN)
- Low RDS(ON) internal switches, short-circuit protected
- Current mode operation for excellent line and load transient response
- Low dropout operation: 100% duty cycle, power good output
- Quiescent current in sleep mode is 125µA typical
- Ultralow shutdown current is 1µA maximum at (VRUN1 = VRUN2 = 0V)
- Phase pin selects 2nd channel phase relationship with respect to 1st channel
- Internal soft-start with individual run pin control
- Operating temperature is -40°C to 85°C, package style is 20-lead plastic TSSOP
