3A LOW NOISE STEP-DOWN DC-DC CONVERTER
Description
The PAM2307 is a 3A step-down DC-DC converter. At heavy load,
the constant-frequency PWM control performs excellent stability and
transient response. No external compensation components are
required.
The PAM2307 supports a range of input voltages from 2.7V to 5.5V,
allowing the use of a single Li+/Li-polymer cell, multiple Alkaline/
NiMH cell,and other standard power sources. The output voltage is
adjustable from 0.6V to the input voltage. The PAM2307 employs
internal power switch and synchronous rectifier to minimize external
part count and realize high efficiency. During shutdown, the input is
disconnected from the output and the shutdown current is less than
1µA. Other key features include over-temperature and short circuit
protection, and under-voltage lockout to prevent deep battery
discharge.
The PAM2307 delivers 3A maximum output current while consuming
only 42µA of no-load quiescent current. Ultra-low RDS(ON) integrated
MOSFETs and 100% duty cycle operation make the PAM2307 an
ideal choice for high output voltage, high current applications which
require a low dropout threshold.
The PAM2307 is available in QFN3x3 16-Pin and SOP-8(EP)
package.

Function
Main power ground pin.
Feedback voltage to internal error amplifier, the threshold voltage is 0.6V.
Signal ground for small signal components.
No connection.
Enable control input. Force this pin voltage above 1.5V, enables the chip, and
below 0.3V shuts down the device.
Test Mode(no connect or to Ground).
Bias supply. Chip main power supply pin.
Input supply for power stage. Must be closely decoupled to PGND.
The drains of the internal main and synchronous power MOSFET.
