1.5µA IQ, Step-Up DC-DC Converters

in Thin SOT23-5

ELECTRICAL CHARACTERISTICS (continued)

(VBATT = 1.2V, VOUT = 3.3V (MAX1722/MAX1723), VOUT = VOUT(NOM) (MAX1724), SHDN = OUT, RL =

∞, TA = 0°C to +85°C,

unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: Limits are 100% production tested at TA = +25°C. Limits over the operating temperature range are guaranteed by design.

Note 2: Guaranteed with the addition of a Schottky MBR0520L external diode between LX and OUT when using the MAX1723

with only one cell, and assumes a 0.3V voltage drop across the Schottky diode (see Figure 3).

Note 3: Supply current is measured with an ammeter between the output and OUT pin. This current correlates directly with actual

battery supply current, but is reduced in value according to the step-up ratio and efficiency.

Note 4: VOUT forced to the following conditions to inhibit switching: VOUT = 1.05 ✕ VOUT(NOM) (MAX1724), VOUT = 3.465V

(MAX1722/MAX1723).
