LTC3310S - 5V, 10A Synchronous Step-Down Silent Switcher 2
in 3mm × 3mm LQFN
The LTC3310S is a very small, low noise, monolithic step-down DC/DC converter capable of providing up to 10A
of output current from a 2.25V to 5.5V input supply. The device employs Silent Switcher 2 architecture with inter-
nal hot loop bypass capacitors to achieve both low EMI and high efficiency at switching frequencies as high as
5MHz. For systems with higher power requirements, multi-phasing parallel converters is readily implemented.
The LTC3310S uses a constant-frequency, peak current mode control architecture for fast transient response. A
500mV reference allows for low voltage outputs. 100% duty cycle operation delivers low drop out.
Other features include a power good signal when the output is in regulation, precision enable threshold, output
overvoltage protection, thermal shutdown, a temperature monitor, clock synchronization, mode selection and out-
put short circuit protection.
ADP151 - Ultralow Noise, 200 mA, CMOS Linear Regulator
The ADP151 is an ultralow noise, low dropout (LDO) linear regulator that operates from 2.2 V to 5.5 V and pro-
vides up to 200 mA of output current. The low 135 mV dropout voltage at 200 mA load improves efficiency and
allows operation over a wide input voltage range.
Using an innovative circuit topology, the ADP151 achieves ultralow noise performance without the necessity of a
bypass capacitor, making the device ideal for noise-sensitive analog and RF applications. The ADP151 also achieves
ultralow noise performance without compromising the power supply rejection ratio (PSRR) or transient line and
load performance. The low 265 μA of operating supply current at 200 mA load makes the ADP151 suitable for
battery-operated portable equipment.
The ADP151 also includes an internal pull-down resistor on the EN input.
The ADP151 is specifically designed for stable operation with tiny 1 μF, ±30% ceramic input and output capacitors
to meet the requirements of high performance, space constrained applications.
The ADP151 is capable of 16 fixed output voltage options, ranging from 1.1 V to 3.3 V.
Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP151 is availa-
ble in tiny 5-lead TSOT, 6-lead LFCSP, and 4-ball, 0.4 mm pitch, halide-free WLCSP packages for the smallest
footprint solution to meet a variety of portable power application requirements.
STUSB4500 - USB 3.0 Power Delivery
The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algo-
rithm to allow the negotiation of a power delivery contract with a source without MCU support (auto-run mode).
PDO profiles are configured in an integrated non-volatile memory.
