Analog Devices
Synchronous Step-Down DC-DC Converter
The ADP2102 is a synchronous step-down dc-to-dc converter that converts a 2.7 V to 5.5 V unregulated input voltage to a lower regulated output voltage with up to 95% efficiency and 1% accuracy. The low duty cycle capability of the ADP2102 is ideal for USB applications or 5 V systems that power up submicron subvolt processor cores. Its 3 MHz typical operating frequency and excellent transient response allow the use of small, low cost 1 µH inductors and 2.2 µF ceramic capacitors. At medium-to-high load currents, it uses a current mode, pseudofixed frequency pulsewidth modulation to extend battery life. To ensure the longest battery life in portable applications, the ADP2102 has a power save mo...

Synchronous Step-Down DC-to-DC Regulator
The ADP2114 is a versatile, synchronous step-down, switching regulator that satisfies a wide range of customer point-of-load requirements. The two PWM channels can be configured to deliver independent outputs at 2 A and 2 A (or 3 A/1 A) or can be configured as a single interleaved output capable of delivering 4 A. The two PWM channels are 180º phase shifted to reduce input ripple current and to reduce input capacitance. The ADP2114 provides high efficiency and operates at switching frequencies of up to 2 MHz. At light loads, the ADP2114 can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode to reduce EMI. The ADP2114 is designed with an optimized gate slew rate ...
